Product FAQs
5 answersWhat equipment is the Federal Pacific NJL631225R designed to fit?
This N-frame molded case circuit breaker is an exact replacement for legacy Federal Pacific motor control centers and industrial switchboards. It installs directly into existing enclosures without requiring aftermarket adapters or panel modifications.
What does the R suffix indicate in the NJL631225R part number?
The R signifies that this specific breaker model features a built-in rotary handle mechanism. This handle configuration is typically required for proper operation and external actuation within Federal Pacific motor control center buckets.
What conductor sizes are accepted by the factory lugs on the NJL631225R?
The standard load-side lugs on this breaker accommodate wire gauges ranging from 6 AWG up to 350 kcmil. Always verify proper torque specifications during installation to ensure a secure and compliant connection.
Does the NJL631225R share the same design as residential Stab-Lok breakers?
No. The NJL631225R is a commercial and industrial N-frame molded case circuit breaker designed for heavy-duty switchboards and motor control centers. It operates on a completely different platform and does not use the residential Stab-Lok design.
Can the trip settings on the NJL631225R be adjusted in the field?
No. This breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous overcurrent protection thresholds are permanently set at the factory and cannot be modified during installation.
