Note: On certain models with UL/CSA labeling the thermal trip setting is fixed and only the magnetic trip (instantaneous) setting is adjustable.
Accessories
Notes on mounting and wiring Auxiliary Switches for UL/CSA labeled models:
- M22-K(10)(01) have screw terminals. M22-CK(10)(01)(20)(02)(11) have clamp terminals.
- Switch modules are snapped into place at the locations shown in the diagrams that follow.
- Switches will function as either “standard” or “trip/alarm” contacts depending on their mounting location.
- Location “HIN” refers to standard operation. Location “HIA” refers to “trip/alarm” operation.
- Follow the numbering and wiring scheme provided above depending on the contact location and function. (N.O. or N.C.)
- Permissible contact configuration: 1 HIA and/or 2 HIN.
Note:
After mounting of the M22… switch is complete, check off the appropriate box on the auxiliary switch label provided on the side of the breaker or switch.
