Product FAQs
6 answersWhich panelboards are compatible with the NE237020 circuit breaker?
The NE237020 is a bolt-on N-Frame breaker designed exclusively for legacy Federal Pacific NE panelboards. It is an industrial molded case breaker and will not fit standard FPE Stab-Lok residential load centers.
What wire gauge is accepted by the lugs on the NE237020?
The integrated lugs accept wire sizes from 14 AWG to 10 AWG. Always verify that the wire material and size comply with local electrical codes for a 20-amp circuit before installation.
Is the Federal Pacific NE237020 still being manufactured?
Federal Pacific Electric is no longer in business, meaning original NE-frame breakers are obsolete and no longer in active production. They are sourced through specialized distributors to support and maintain existing legacy infrastructure.
Can the NE237020 be used in DC applications?
Yes, in addition to its standard 240VAC rating, this thermal-magnetic breaker is rated for up to 250VDC. When used in direct current systems, it provides a 5kA interrupting capacity.
Does the NE237020 feature an adjustable trip setting?
No, this breaker utilizes a fixed thermal-magnetic trip mechanism. Both the long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
Are Federal Pacific NE frame breakers part of the Stab-Lok safety issues?
The widely documented safety concerns and failure rates associated with Federal Pacific Electric primarily involve their residential Stab-Lok load centers and breakers. The NE237020 is a commercial N-Frame molded case circuit breaker, which utilizes a different internal design. Regardless, all legacy electrical equipment should be routinely inspected by a qualified professional.
