Product FAQs

7 answers
What does the "WL" suffix indicate on the THFK236125WL catalog number?

The "WL" suffix designates that the circuit breaker ships with factory-installed copper/aluminum (Cu/Al) lugs on both the line and load terminals.

What equipment is compatible with the THFK236125WL circuit breaker?

This F-Frame breaker is designed for unit-mount installations in legacy General Electric A-Series panelboards, switchboards, motor control centers, and standalone enclosures.

What conductor sizes are supported by the terminals on this breaker?

The factory-installed lugs accommodate copper or aluminum wire sizes ranging from 4 AWG up to 300 kcmil.

Is the THFK236125WL suitable for direct current (DC) applications?

Yes, in addition to its AC ratings, this breaker is rated for DC systems. It provides a 10kA interrupting capacity at both 250VDC and 500VDC.

What is the mounting configuration for the THFK236125WL?

This is a feed-thru, unit-mount circuit breaker. It requires a bolt-on installation method and does not plug directly into a busbar.

Why is this breaker listed under both ABB and General Electric?

Following ABB's acquisition of GE Industrial Solutions, legacy GE breakers like the THFK236125WL may carry either ABB or GE branding depending on the production date. The form, fit, and function remain identical regardless of the label.

How does the trip unit operate on the THFK236125WL?

It utilizes a thermal-magnetic trip mechanism with LI (Long-Time and Instantaneous) functions. The thermal element provides fixed overload protection, while the magnetic element offers adjustable short-circuit protection.
