Product FAQs

6 answers
What types of equipment are compatible with the L3600?

This breaker is specifically designed for integration into legacy Westinghouse panelboards, switchboards, and motor control centers that accept unit-mount, bolt-on breakers.

Is the L3600 an exact replacement for other legacy Westinghouse breakers?

Yes, this unit acts as a direct substitute for legacy LA3600 and LD3600 molded case circuit breakers. It shares the same physical footprint, allowing for straightforward maintenance in older electrical systems.

What wire sizes do the included lugs accommodate?

The factory-installed load-side lugs are designed to accept two 250 to 500 kcmil conductors per pole, allowing for parallel cable runs in high-amperage applications.

How does the adjustable magnetic trip function work on this breaker?

The thermal-magnetic trip unit features a fixed thermal element for standard overload protection, paired with an adjustable magnetic element. This allows electricians to fine-tune the instantaneous short-circuit response based on the specific load characteristics.

Can this breaker be used in DC applications?

Yes, while primarily used in AC systems, this breaker is also rated for direct current applications up to 250VDC with a 10kA interrupting capacity.

How is the L3600 breaker mounted in an enclosure?

It utilizes a unit-mount, bolt-on configuration. This requires a hardwired connection directly to the panel bus or mounting pan, rather than snapping onto a DIN rail or plug-on bus.
