INTRODUCTION
This installation instruction is for Cutler-Hammer C361, C371 (variable depth) mechanisms. These mechanisms are for disconnect switches and circuit breakers mounted in Hoffman two-door, floor-mounted, enclosures with the disconnect on the right flange.
Master Door
INSTALLATION STEPS
Step 1 – Position mounting plate (item1) on the inside of the enclosure, behind the opening provided.
Step 2 – Discard the Cutler-Hammer spring bracket which is normally installed inside the enclosure flange, behind the C-H handle mechanism.
Step 3 – Assemble the Cutler-Hammer handle mechanism through the opening in the enclosure and through the mounting plate. Omit cap screw and lockwasher which fits into bottom hole of the handle mechanism.
Step 4 – Install the slide arm (item 2) through the slot in the bottom of mounting plate (item 1) and over the defeater part of the handle assembly (on C-H handle mechanism). Place the smaller diameter end of the shoulder collar (item 3) through the oval slot in the slide arm. Install long cap screw (item 4) with lockwasher (item 5) through shoulder collar into the bottom mounting hole of the C-H handle mechanism and tighten. The slide arm and defeater should move up and down smoothly. Install door hasp (C-H part) per Cutler-Hammer instructions.
Step 5 – Attach the bottom of the slide arm (item 2) to the offset arm of the lock release mechanism. Use two flat washers (item 6), two lockwashers (item 7), and two hex nuts (item 8). Do not tighten until parts are adjusted. (see Step 6 – (B) )
Step 6 – The handle safety lock release mechanism is adjustable in two places.
(A) Check the adjustment of the factory installed roller bracket. The door latch should hit against the latch stop portion of the roller bracket when the door is closed and latched. Adjust up or down if necessary. The attached mechanism will then provide the necessary up-down motion required to operate the release mechanism in the C-H handle mechanism.
(B) Adjust the length of the slide arm assembly. With proper adjustment of the slide arm, the safety lock (on Cutler- Hammer handle mechanism) should release just before the master door is fully latched. Lengthen slide arm if safety lock releases too soon. Shorten slide arm if safety lock releases too late.
Step 7 – Attach the door catch (item 9), provided by Hoffman, to the tapped spacer on the door using the bottom set of mounting holes. Use two screws (item 10) and lockwashers (item 11). The door catch prevents the door from being opened when the handle mechanism is in the “ON” position. The door catch may be easily bent up or down to hook properly on the door hasp of the Cutler- Hammer handle mechanism.
Step 8 – Drill and tap holes in panel as shown in diagram and table 1. See Cutler-Hammer instructions for locating extra holes for fuse clips.
Step 9 – Mount switch or circuit breaker using Cutler-Hammer instructions and parts. C-H connecting rod must be cut off per Cutler-Hammer instructions. See table 2 for depth dimensions used to determine length of rod.

INTRODUCTION
This installation instruction is for Cutler-Hammer C361, C371 (variable depth) mechanisms. These mechanisms are for disconnect switches and circuit breakers mounted in Hoffman two-door, floor-mounted, enclosures with the disconnect on the centerpost.
Master Door
INSTALLATION STEPS
Step 1 – Position Mounting plate (item 1) on the inside of the enclosure, behind the opening provided in the centerpost.
Step 2 – Discard the Cutler-Hammer spring bracket which is normally installed inside the enclosure flange behind the C-H handle mechanism.
Step 3 – Assemble the Cutler-Hammer handle mechanism through the opening in the enclosure and through the mounting plate. Omit cap screw and lockwasher which fits into bottom hole of operating handle.
Step 4 – Cut 2 1/2″ off bottom end of slide arm (item 2). (bottom end has rectangular holes only)
Step 5 – Install the slide arm (item 2) through the slot in the bottom of mounting plate (item 1) and over the defeater part of the handle assembly (on C-H handle mechanism). as shown. Place the smaller diameter end of the shoulder collar (item 3) through the oval slot in the slide arm. Install long cap screw (item 4) with lockwasher (item 5) through shoulder collar into the bottom mounting hole of the C-H handle mechanism and tighten. The slide arm and defeater should move up and down smoothly. Install door hasp (C-H part) per Cutler-Hammer instructions.
Step 6 – Attach the bottom of the slide arm (item 2) to the offset arm of the lock release mechanism. Use two flat washers (item 6), two lockwashers (item 7), and two hex nuts (item 8). Do not tighten until parts are adjusted.
Step 7 – Adjust the length of the slide arm assembly. With proper adjustment of the slide arm, the safety lock (on Cutler-Hammer handle mechanism) should release just before the master door is fully latched. Lengthen slide arm if safety lock releases too soon. Shorten slide arm if safety lock releases too late.
Step 8 – Attach the door catch (item 9), provided by Hoffman, to the tapped spacer on the door using the bottom set of mounting holes. Use two screws (item 10) and lockwashers (item 11). The door catch prevents the door from being opened when the handle mechanism is in the “ON” position. The door catch may be easily bent up or down to hook properly on the door hasp of the Cutler- Hammer handle mechanism.
Step 9 – Drill and tap holes in panel as shown in diagram and table 1. See Cutler-Hammer instructions for locating extra holes for fuse clips.
Step 10 – Mount switch or circuit breaker using Cutler-Hammer instructions and parts. Cutler-Hammer connecting rod assembly must be cut off per Cutler-Hammer instructions. See table 2 for depth dimensions used to determine length of rod.

INSTALLATION STEPS
Step 1 – Discard Hoffman mounting plate (item 1) which is not required for this installation.
Step 2 – Assemble the Cutler-Hammer Flex ShaftTM handle mechanism and cable toggle mechanism to the enclosure flange opening. Omit cap screw and lockwasher which fits into bottom hole of Cutler-Hammer handle mechanism.
Step 3 – Modify slide arm (item 2) only if it is being installed in an enclosur e with disconnect on centerpost. (cut 2.5 inches off the bottom end of slide arm. Bottom end has rectangular holes only)
Step 4 – Install the slide arm (item 2) over the defeater part of the handle assembly (on C-H handle mechanism). Place the smaller diameter end of the shoulder collar (item 3) through the oval slot in the slide arm. Install long cap screw (item 4) with lockwasher (item 5) through shoulder collar into the bottom mounting hole of the C-H handle mechanism and tighten. The slide arm and defeater should move up and down smoothly. Install door interlock lever (C-H part) per Cutler-Hammer instructions.
Step 5 – Attach the bottom of the slide arm (item 2) to the offset arm of the lock release mechanism. Use two flat washers (item 6), two lockwashers (item 7), and two hex nuts (item 8). Do not tighten until parts are adjusted. (see Step 6 – (B) )
Step 6 – The handle safety lock release mechanism is adjustable.
(A) Check the adjustment of the factory installed roller bracket on enclosures with disconnect on right flange. The door latch should hit against the latch stop portion of the roller bracket when the door is closed and latched. Adjust up or down if necessary. The attached mechanism will then provide the necessary up-down motion required to operate the release mechanism.
(B) Adjust the length of the slide arm assembly. With proper adjustment of the slide arm, the safety lock (on Cutler- Hammer handle mechanism) should release just before the master door is fully latched. Lengthen slide arm if safety lock releases too soon. Shorten slide arm if safety lock releases too late.
Step 7 – Attach the door catch (item 9), provided by Hoffman, to the tapped spacer on the door using the bottom set of mounting holes. Use two screws (item 10) and lockwashers (item 11). The door catch prevents the door from being opened when the handle mechanism is in the “ON” position. The door catch may be easily bent up or down to hook properly on the door interlock lever of the Cutler-Hammer handle mechanism.
Step 8 – Assemble the C-H linkage between outer handle assembly and the toggle mechanism (inside). See C-H Flex ShaftTM instructions.
Step 9 – Drill and tap holes in panel as shown in diagram and table. See Cutler-Hammer instructions for locating holes.
Step 10 – Mount circuit breaker and actuator mechanism using Cutler-Hammer Flex ShaftTM instructions and parts.
