ABB / General Electric THLC234150 Molded Case Circuit Breaker

This bolt-on circuit breaker is designed for use in GE Spectra Series and A-Series panelboards, as well as compatible GE switchboards and motor control centers.

As a current limiting breaker, it is engineered to quickly interrupt severe fault currents. This restricts the let-through energy, protecting downstream wiring and sensitive equipment from thermal and mechanical damage during a short circuit.

Yes, this breaker features a thermal magnetic trip unit with a fixed thermal element for standard overload protection and an adjustable magnetic element. This allows you to fine-tune the instantaneous short circuit trip response to match your specific load requirements.

The factory-installed lugs accept copper or aluminum conductors ranging from 4 AWG up to 300 kcmil. Ensure you use the proper torque specifications when terminating the wires.

The LI designation means the thermal magnetic trip unit includes Long-Time (L) protection for continuous overloads and Instantaneous (I) protection for immediate short circuit clearing.

Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment. It is also UL 489 listed for standard commercial and industrial applications.

A 200kAIC rating is required in heavy commercial and industrial environments where the available fault current from the utility or local transformers is exceptionally high. This ensures the breaker can safely clear massive short circuits without sustaining catastrophic damage.

Yes, as a bolt-on breaker, it requires the appropriate mounting hardware specific to the GE Spectra or A-Series panelboard, switchboard, or motor control center where it is being installed.
