Paneltronics 'A' Frame Magnetic Circuit Breaker - 20 Amps - Single Pole

The Paneltronics 'A' Frame Magnetic Circuit Breaker – 20 Amps, Single Pole is a professional-grade electrical protection component engineered for marine and mobile power distribution systems. This 20-amp single-pole breaker serves as a standard branch circuit protector in Paneltronics electrical distribution panels, meeting rigorous American Boat and Yacht Council (ABYC) standards for non-ignition-protected applications. The unit is UL Recognized (UL 1077) for U.S. use and CSA Certified for Canadian installations, ensuring compliance with stringent electrical safety codes.

The breaker's magnetic trip mechanism provides reliable overcurrent protection for both AC and DC circuits, critical in environments where power stability directly impacts operational readiness. The trip-free design (conforming to ABYC E-11.12.1.7.2.2 and E-11.12.2.8.1) ensures the breaker automatically disconnects if the handle is manually held in the ON position during a fault condition—a safety feature that prevents dangerous workarounds on active circuits. Manual reset operation requires deliberate operator intervention to restore power, eliminating the risk of automatic reconnection after a protection event and maintaining control over circuit restoration protocols.

This breaker is specified for marine vessels, offshore platforms, expedition vehicles, and other installations requiring dual AC/DC circuit protection in confined electrical panels. The compact 2 × 2 × 2 inch footprint and lightweight 0.2 lb design integrate seamlessly into space-constrained panel configurations without adding significant weight—a consideration in weight-sensitive maritime and mobile applications. Operators and marine electricians standardizing on Paneltronics panel architecture will find this breaker a direct fit for routine maintenance and system expansion, eliminating compatibility concerns and reducing installation time in field environments.
