Frequently Asked Questions

What is the GE Thermal Unit 20 Trip Class used for?

The GE Thermal Unit 20 Trip Class is an overload protection device used in motor starters and contactors. It protects electric motors from damage due to prolonged overcurrent conditions by tripping the circuit when excessive heat is detected, ensuring reliable operation in industrial and commercial applications.

What are the specifications of the GE Thermal Unit CR123F772B?

The GE Thermal Unit CR123F772B has a 20 Trip Class rating, designed for use with GE motor starters. The manufacturer part number is CR123F772B. It provides thermal overload protection by responding to heat buildup, with a trip class indicating the maximum time to trip under locked rotor conditions.

Where to buy the GE Thermal Unit CR123F772B worldwide?

You can source the GE Thermal Unit CR123F772B through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine GE components for your motor protection needs.

How to select the correct GE Thermal Unit for a motor starter?

To select the correct GE Thermal Unit, match the trip class (e.g., 20) to your motor's starting characteristics and full-load current. Consult the motor nameplate and starter manufacturer's selection table. For the CR123F772B, verify compatibility with your GE starter model. 3G Electric can assist with sourcing the right unit.
