NEMA 1 circuit breaker enclosures provide reliable protection for indoor electrical systems in commercial and light-industrial environments. These steel housings are designed to accept molded-case circuit breakers (MCCBs) such as Noark’s Ex9 M-Series, ensuring compliance with CSA C22.2 and UL 489 standards. Each enclosure includes mounting brackets, knockouts, and padlockable handles for safe operation and maintenance.
Use NEMA 1 enclosures for breaker assemblies, service entrance disconnects, and feeder protection where environmental exposure is minimal.
