Product FAQs
6 answersWhat type of enclosures accept the NJL632225 breaker?

What wire sizes are compatible with the terminals on this breaker?
The load side lugs on this breaker accept wire gauges ranging from 6 AWG up to 350 kcmil. Always verify that your conductor material and insulation are rated for the application and follow standard torque specifications during installation.
How does the adjustable magnetic trip function work on this model?
The NJL632225 features a thermal magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element. The adjustable magnetic setting allows electricians to fine-tune the instantaneous short-circuit response to suit specific load requirements.
