Description
Stab-Lok circuit breakers are one, two, and three pole thermal magnetic circuit breakers that provide arc fault circuit interrupters for Federal Pioneer panels. They have easy to read color coded handles to differentiate ampere ratings. This breaker is a one pole 20A, 120/240VAC moulded case breaker with bolt on mounting. This circuit breaker meets CSA standards.
Features
- The Schneider Electric (Federal Pioneer) NB20 is a 20-Amp, 1-pole thermal-magnetic circuit breaker. Unlike the common "plug-in" (NA series) Stab-Lok breakers found in homes, the NB series features a bolt-on mounting design. It is specifically engineered for Federal Pioneer (FPE) commercial and industrial load centers or panelboards where a secure, bolted mechanical connection is required to withstand high-vibration or heavy-duty environments.
- Rated for 20 Amps at 120/240V AC, the NB20 is the staple choice for protecting commercial lighting circuits, office receptacles, and small appliances. In Canadian commercial settings, this breaker provides the precise overcurrent protection needed to prevent wiring from overheating while maintaining the integrity of the 120V branch system.
- Equipped with a 10,000 Amp (10kA) interrupting rating, the NB20 can safely clear significant electrical faults. This is a critical requirement for commercial buildings in Canada, where the proximity to large utility transformers means the available short-circuit current is often higher than what a standard residential breaker could safely handle.
- Following the classic Federal Pioneer design language, the NB20 features a color-coded handle (typically Blue for 20A). This allows maintenance staff and electricians to instantly verify the circuit's amperage rating in a crowded panelboard without having to read small printed text, significantly speeding up troubleshooting and panel audits.
- The bolt-on design of the NB20 provides a superior electrical and mechanical bond to the panel's bus bar. This eliminates the risk of "arcing" or loosening that can occur with plug-in breakers under heavy, continuous loads. It is the preferred standard for Canadian hospitals, schools, and office towers where permanent, high-integrity connections are mandatory.
