Product FAQs
5 answersWhich panelboards and switchboards are compatible with the NJL632350?
This breaker is designed to bolt directly into legacy Federal Pacific switchboards and panelboards configured for N-frame molded case circuit breakers.
What are the acceptable wire sizes for the lugs on the NJL632350?
The terminal lugs accommodate either a single conductor ranging from 2/0 AWG to 500 kcmil, or dual conductors ranging from 2/0 AWG to 250 kcmil per phase.
How does the adjustable magnetic trip function operate on this breaker?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element. This allows electricians to dial in the instantaneous short-circuit pickup level to coordinate with downstream devices.
Is the Federal Pacific NJL632350 still actively manufactured?
No, Federal Pacific is an obsolete brand. Exact replacements are sourced from legacy inventory to maintain existing electrical infrastructure without requiring a full panelboard retrofit.
How is the NJL632350 secured within the panelboard?
It utilizes a bolt-on connection type, meaning the line-side terminals must be mechanically bolted directly to the panelboard busbars. Proper torque must be applied to ensure a secure, low-resistance connection.
