Paneltronics 'A' Frame Magnetic Circuit Breaker - 50 Amps - Single Pole

The Paneltronics 'A' Frame Magnetic Circuit Breaker—50 Amps, Single Pole (Part Number 206-077S)—is a standard branch circuit protection device engineered for AC and DC electrical distribution systems. Built to meet American Boat and Yacht Council (ABYC) standards for non-ignition-protected applications, this single-pole breaker provides reliable overcurrent protection in marine electrical panels and other demanding electrical systems requiring certified, trip-free operation.

Rated at 50 amps, this magnetic circuit breaker is designed for standard branch circuit protection in Paneltronics electrical distribution panels. The unit carries UL 1077 recognition for use in the United States and CSA certification for Canadian applications, ensuring compliance with the stringent safety requirements outlined in ABYC standard E-11.12. The trip-free design (meeting ABYC E-11.12.1.7.2.2 and E-11.12.2.8.1) guarantees that manual operation cannot override trip action during fault conditions, a critical safety feature in marine and industrial electrical systems. Manual reset operation requires deliberate operator intervention, preventing automatic re-engagement after a fault condition clears.

This breaker is intended for marine installations, offshore vessels, and AC/DC electrical systems where ABYC compliance is mandatory. Technicians and marine electricians rely on Paneltronics breakers for retrofit and new installations where certified protection against electrical overload and short circuits is required. The single-pole configuration suits branch circuit applications where individual load protection is needed without requiring multi-pole coordination.

Paneltronics circuit breakers are widely recognized in the marine electrical aftermarket as a standard replacement component for both original equipment and legacy system upgrades. The 50-amp rating accommodates medium-load branch circuits in electrical distribution environments where manual reset protection and trip-free safety mechanisms are non-negotiable.
