Frequently Asked Questions

What is the GE CR123F658B thermal unit used for?

The GE CR123F658B thermal unit is an overload protection device used in motor starters and contactors. It provides 20 Trip Class protection, meaning it delays tripping during high-inrush starts to prevent nuisance shutdowns while safeguarding motors from sustained overcurrent damage.

What are the specifications of the GE CR123F658B thermal unit?

The GE CR123F658B thermal unit has a 20 Trip Class rating and manufacturer part number CR123F658B. It is designed for use with GE motor starters to provide thermal overload protection. For exact current range and compatibility, consult the product datasheet or contact 3G Electric.

Where to buy the GE CR123F658B thermal unit worldwide?

You can source the GE CR123F658B thermal unit through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact our team for pricing and lead time on this part.

How to select the correct GE thermal unit for a motor starter?

Select the GE thermal unit by matching the motor full-load current (FLA) to the unit's trip range and choosing the appropriate Trip Class. The CR123F658B with 20 Trip Class suits motors with moderate starting current. Always verify compatibility with your specific GE starter model before ordering.
