Product FAQs
6 answersWhich panelboards are compatible with the Federal Pacific NES2330 circuit breaker?
This breaker is engineered specifically for legacy Federal Pacific Stab-Lok panelboards that accept NE-S frame components. It is designed to restore power distribution in older commercial and industrial systems without requiring a complete panel upgrade.
How does the NES2330 connect to the panel busbar?
It features a stab-type plug-on mounting design. This allows the breaker to be installed directly into compatible Federal Pacific enclosures without the need for specialized hardware or modifications to the existing infrastructure.
What type of trip mechanism does the NES2330 utilize?
This unit features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous (LI) functions. It provides standard protection against overloads and short circuits up to its rated interrupting capacity of 18kA at 240V AC and 5kA at 250V DC.
What alternate catalog numbers correspond to the NES2330?
This 30-amp, 3-pole breaker is frequently identified by alternate part numbers including FPE2330 and 2330-R. It serves as an exact drop-in replacement for legacy NE-S frame variants, maintaining the original dimensions required for older infrastructure.
What wire sizes are accepted by the load side terminals on the NES2330?
The included load side lug terminals are designed to accommodate wire gauges ranging from 14 AWG to 10 AWG. Installers must ensure proper torque is applied to the lugs to maintain a secure connection.
What should be inspected when replacing a breaker in a Federal Pacific Stab-Lok panel?
Because Stab-Lok panels are legacy systems, electricians should carefully inspect the panel busbars for any signs of arcing, pitting, or loose connections before installing the replacement breaker. Ensuring the stab connections are secure is critical for safe operation.
