Paneltronics Breaker 50 Amps w/Reverse Polarity Trip Coil - White

The Paneltronics Breaker 50 Amps with Reverse Polarity Trip Coil is a shore main AC circuit breaker engineered for marine electrical distribution panels. Rated at 50 amps, this breaker simultaneously breaks both hot and neutral legs on 120VAC 60Hz systems or both live and neutral legs on 220VAC 50Hz systems, providing critical protection for marine power systems where conventional breakers fall short. The integrated reverse polarity trip coil meets ABYC E-11.6.3.3.1 standards, automatically shutting down the circuit if shore power is connected with reversed polarity—a common cause of catastrophic electrical damage aboard vessels.

Reverse polarity protection works by detecting voltage on the neutral leg when power connections are reversed. When the trip coil senses this dangerous condition, it trips the breaker before current flows to onboard electrical systems. This specification is essential for boat owners who regularly use shore power at different marinas, where aging pedestals or incorrect wiring may present reversed polarity hazards. The white finish blends cleanly into modern panel layouts, and the compact 2x2x2-inch footprint fits standard Paneltronics distribution panel cavities without modification.

This breaker is built for liveaboards, offshore cruisers, and commercial fishing operations where electrical reliability directly impacts safety and vessel systems integrity. Marina connections vary widely in installation quality; a reverse polarity protection breaker eliminates that variable and protects against shore power failures that could disable navigation systems, refrigeration, or critical safety equipment. Installation requires a compatible surge arrestor (P/N 281-001, sold separately) to complete the reverse polarity protection circuit. Part number 206-353 is the original equipment reference for Paneltronics systems.
