Product FAQs
8 answersWhat equipment is the THLC236225 compatible with?
It is designed for use in General Electric switchboards and motor control centers that accept THLC2 frame bolt-on circuit breakers.
Can this breaker be used in standard residential load centers?
No. This is an industrial-grade bolt-on circuit breaker designed specifically for commercial GE switchboards and motor control centers, not residential plug-in load centers.
What does the THLC2 designation mean?
It indicates the breaker belongs to the General Electric THLC2 frame size, which typically covers amperage ratings from 125A to 225A and features current-limiting capabilities.
Are the trip settings adjustable on this model?
No, the THLC236225 features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip thresholds are factory-set and cannot be adjusted in the field.
Can I use aluminum wiring with the factory lugs?
Yes, the included lugs are dual-rated for both copper and aluminum conductors ranging from 4 AWG to 300 kcmil.
What is the benefit of a current-limiting circuit breaker?
As a current-limiting breaker, it restricts the peak let-through current and energy during a fault. This provides enhanced short-circuit protection and reduces thermal and magnetic stress on downstream electrical components.
Does this breaker provide ground fault protection?
No, the THLC236225 is equipped with a standard thermal-magnetic trip unit for overload and short-circuit protection. It does not include integrated equipment ground fault protection.
What safety precautions are required before installing this breaker?
Ensure the switchboard or motor control center is completely de-energized and properly locked out before installation. Only qualified electrical personnel should bolt the breaker to the busbars and torque the terminal lugs to the manufacturer specifications.
