Contactors & Starters Introduction

Broad Line
A wide array of contactors, relays, accessories, enclosures, and assembled starters give you greater design versatility.


Broad Features
C-2000 Control components are loaded with features that make them easier to install, allow more flexible configurations, lower inventory requirements, and make better use of panel space. And their performance is second to none.


Broad Applications
C-2000 components conform to international standards (UL, cUL, and IEC-947) and have dual (U.S./European) markings to ensure global acceptance. A single nomenclature system allows simple sourcing worldwide. AC coils (both 50 Hz and 60 Hz versions) and DC coils are available for a wide range of voltages for flexibility.


Selection Instructions

The C-2000 Starters & Contactors line offers ordering flexibility. Below are detailed instructions for ordering individual components—contactors, overloads, control relays, and accessories.


When the phase, horsepower, voltage, frequency, and full-load amps have been established (assuming AC-3 motor duty category), use the following steps as a guide to ordering:

Step 1. Refer to contactor selection tables on pages 5-38 to 5-45. Select the correct table based upon number of poles (3 or 4), nonreversing or reversing, and coil operation (ac or dc).
Step 2. Using the above motor characteristics, select the appropriate contactor product number.
Step 3. Select correct coil suffix digit or letter from corresponding Coil Selection table.
Step 4. To complete product number, replace asterisk (*) or crosshatch (#) with the selected coil suffix.

If the motor duty is other than category AC-3, refer to the application life curves on pages 5-78 to 5-80 for selection of contactor.


Overload Relays
Step 1. Using the Overload Relay selection tables on pages 5-54 to 5-56, select the correct Overload Relay based on the following criteria: Manual/Automatic with/without Stop or Manual Only Class 10, 20, or Class 30 Contactor frame size Motor full-load amps (Select the overload in which the motor FLA falls within the overload current range.)
Step 2. Select necessary accessories from the Accessories section, page 5-57


Control Relays
Step 1. Select control relay from selection table on page 5-63. Selection is based upon: —Contact arrangement (number of normally open and normally closed contacts) —AC or DC coil controlled
Step 2. Select correct coil suffix symbol from corresponding Coil Selection table.
Step 3. To complete product number, replace asterisk (*) with the selected coil suffix.
Step 4. Select control relay accessories from Control Relay Accessories section on pages 5-64 to 5-66.


Select any required accessories from the Accessories section, pages 5-46 to 5-50.


IEC Contactors C-2000

Three and four poles contactors with electronic modules

150 to 780A (AC3) - 200 to 1000A (AC1)

The focus of GE Industrial Solutions’ engineers when upgrading the electronic module for CK was Reliability and Simplification. They collected all field experience of the successful CK contactor range to keep improving specifications and performance in the most demanding applications for contactors.


Cover a greater range with less references. With only 4 coils the new electronic module covers a range from 24V -30% up to 500V +10% (AC 50/60Hz and DC). The 4 new coils cover the same range that was previously done with 20. This means a reduction in stock, easier management of inventory for distributors and better service which will ensure increased availability to the end customer. The electronic module has been designed to support customer requests to perform successfully in the most difficult applications.


24-60V (AC 50/60Hz and DC):
With special reinforce of the lower range (-30%) solving typical application issues when using big contactors with 24V supply.


48-130V (AC 50/60Hz and DC):
Covers the most common voltages used in transportation segment with only one contactor


100-250V (AC 50/60Hz and DC):
This range replaces the most popular automation voltages; 110-120VAC, 125VDC (MV application) and 220-240VAC, allowing OEM, Distributors and PB to optimize their stocks and service the end customer.


250-500V (AC 50/60Hz and DC):
Typical voltage for Power Switching application. This contactor helps OEMs in UPS, Data Centers and Power Quality applications to standardize their machines to be sold worldwide.


The new electronic module redesign from GE provides much better reliability versus any previous electronic modules or pure mechanical systems. This will help customers to reduce production shortages and keep maintenance downtimes to a minimum. This new range will be the preferred solution for Original Equipment Manufacturers because they can standardize the Bill Of Materials of their machines to be used worldwide. The CK contactor series with electronic module is the perfect fit for OEMs working on Renewals (Wind, Solar, ATS, UPS), HVAC, Marine, Medium Voltage, Oil & Gas and Transportation. CK is approved UL, CCC and CE.


Features and Benefits

  • Increases mechanical life of the contactor improving reliability of end customer equipment
  • Suitable for weak networks application by including a protecting software to avoid chattering and contactor coil burning
  • Better performance in high vibration application; wind, marine, transportation
  • Increased contact pressure reduces resistance per phase and thermal load
  • Noise reduction even in hard environments with dust and corrosion
  • Transient voltage suppressor built-in
  • Wider temperature range operation: -40º to +70ºC
  • Application up to 3000m without derating
  • Conversion kit for installed CK base with electronic module
  • No dimensions change to facilitate exchange of products
  • Energy efficiency: reduce on hold consumption
  • Compliant with REACH and RoHS directives


IEC Contactors Thermal Overload Relays C-2000

Fixed Heater
C2000 RT overload relays provide motor overload protection through fixed bimetal heaters. These relays are ambient compensated and utilize a differential mechanism for single-phase sensitivity. The trip setting is adjustable for the range listed.


Overload relays may be set for 4 different operational modes—manual reset only, automatic reset only, manual reset/stop, or automatic reset/stop. Stop is initiated by pushing the reset button which interrupts the holding circuit in the latter two listed modes. Overload relays feature visible trip indication, reset on the upstroke, weld check, and trip test.
