2. Multi-function START/STOP pushbutton are standard for General Purpose Type 1(M1) dimensions A and B enclosures.

A.C. Coil Codes & Voltage Ranges 
All catalog numbers, list prices and enclosure dimensions in the previous section reflect contactors with AC coils. If necessary, add the appropriate price adder to the list price for each coil required as shown in the online catalog. Remember that reversing applications require two coils. Price Adder x 2.

All Contactor and Starter Configurations
D.C. Coil Codes & Voltage Ranges ➊➎
For starters with DC coils, select Coil Code from the table below. Remember that reversing applications require two coils (Price Adder x 2). Starter catalog numbers must be modi-fied when using DC coils. For example: For CAT7-9…55 contactors, add an “E” to catalog number for Electronic DC Coils. i.e.: CAT7-9… becomes CAT7-9E… For CAT7-60…97 contactors, add a “D” to catalog number. i.e.: CAT7-60… becomes CAT7-60D…

CAT9 AC/DC Coil Codes and Voltage Ranges ➋➌➎

1. Only the most common coils are shown here. Other coil voltages may be available. Refer to Contactor Renewal Parts in Section A of this catalog, or contact your nearest Sprecher + Schuh sales office.
2. Wide range coil.
3. “-EI” designates contactor coil with PLC input. Selections CA9-116…370 with “EI” requires use of control logic on terminals 1, 2, 3. CA9-400 contactors and larger include an integral switch to select use of “EI”.
4. “DD” coils are standard for CA7-60D…97D.
5. Reversing applications require two coils. Add appropriate price adder(s) to list price of enclosed contactors and starters. Remember to add price for each coil required.
6. CA7-9E…55E electronic coils are not interchangeable with non-electronic DC or AC coils.
7. This coil range is 24-60V DC only.

CA7 Contactor with CEP7 Overload Relay 

CA9 Contactor with Overload Relay ➋

Special Notes:
Wye-Delta Starters – First multiply motor full load current by 58%. Then, using this figure, select appropriate Overload Relay Code from tables above.
Part Winding Starters – First multiply motor full load current by 50%. Then, using this figure, select appropriate Overload Relay Code from tables above.
Variable Frequency Drives – CEP7 solid state overload relays cannot be utilized on VFDs or Softstarters with Braking option.

1. Engineered solution is a pass-thru model overload. No direct contactor mounting for this selection is available within the CEP7-1EE/1EF series.
2. This reference is not intended to be a guide for selecting contactors. Size overload relays using the full load current of the motor.
3. The reset time of a CEP7 set in the automatic mode is approximately 180 seconds.
4. CEP7 Overload relays do not work with Variable Frequency Drives or any Sprecher + Schuh Softstarter with braking options.
5. Utilizes UL approved Current Transformers and a CEP7-1EF_Z overload relay. For CE approved Current Transformers – refer to factory.
6. The letter “P” designates the parameter configuration module and can changed to an “E” to represent the use of Ethernet/IP communication module.

3. See page C112 for detail specifications for Control Circuit Transformer.
4. Refer to factory for pricing on larger oversized control circuit transformer selections.
5. Modifications may change dimension of starter enclosure.
6. Auxiliary addition is per contactor. Quantity is double for reversing applications. Double price adder accordingly.

Ordering Instructions

Replace ✱ in base Catalog Number with Power Supply code. Example: To Add a Standard Capacity Power Supply with Control Circuit Transformer (480/120):
change CAT7-30E-✱-◆-GO to CAT7-30E-PS1XC-◆-G0.

1.  Not applicable for Series CA9 Starters. CAT9 Starter applications should strongly consider the use of the “EI” functionality included in the CA9-116…1060-EI Contactors. The optional electronic interface selection allows the CA9 contactor to be switched from a PLC or other low-level signal source (15…33V DC) without the need of an interposing relay. The current burden of the interface is 15 mA maximum.
2. Modifications may change dimension of starter enclosure.

Sprecher + Schuh is an ISO9001 company. Our panel shops are UL and ATEX Certified.
Please refer to factory for specifications and label options for the following panel certifications.

UL508A or SUSE label: Most starter assemblies can be supplied with a UL508A ‘Industrial Control Panel’ label. Combination starters can be supplied with Suitable for Service Entrance (SUSE) label. The need for a UL508A or SUSE label must be identified at the time of quotation as well as on the purchase order. The need for a UL508A label may not change the components we would normally use but we must consider all possible requirements at the time we are developing the bill-of-material to be referenced at the time of order entry. Failure to identify the need for a UL508A label or SUSE label at the time of quotation may result in change notice price adders.

ATEX Certification: A requirement for ATEX certification MUST be identified at the time of quotation as well as on the purchase order. ATEX certification of a Type 7/9 explosion proof enclosure definitely requires all conduit and cover openings to be drilled by the enclosure manufacturer. Further, all pilot devices and equipment to be installed must be identified as it controls the heat dissipation which is an ATEX certification requirement. Absolutely no field modification of an ATEX certified starter assembly is allowed. Failure to identify the need for an ATEX certification at the time of quotation and order entry may result in 100% cancelation or re-stocking charge since a new enclosure will be required.

UL1203 Certification: The UL1203 label for explosion proof starters and panels encompasses the UL508A certification. This means all components in a UL1203 labeled panel must first comply with UL508A, and all components in the panel must have a UL label in some form, including the wiring. A special name plate and UL508A label are applied to the panel or starter. A panel is not UL1203 certified unless both label and name plate are present. Contact [email protected] for more information on UL1203 certified panels.
