Paneltronics Standard Panel AC Main Double Pole w/30Amp CB & Reverse Polarity Indicator

The Paneltronics Standard Panel AC Main Double Pole with 30 Amp Circuit Breaker and Reverse Polarity Indicator is a marine-grade electrical panel component designed for AC power distribution systems in vessels, RVs, and off-grid installations. This double-pole main breaker unit provides robust overcurrent protection at 30 amps, with integrated reverse polarity detection to prevent damage from incorrect power connections—a critical safety feature in shore power and generator applications.

The 30-amp double-pole configuration handles both legs of a standard 120/240V AC supply, making it the main distribution point for electrical loads aboard marine vessels and mobile platforms. Paneltronics marine electrical panels are engineered to withstand corrosion from salt air and moisture exposure, critical in offshore and coastal environments. The reverse polarity indicator serves as a visual diagnostic tool, alerting operators to wiring faults before they cause expensive equipment damage. Compact dimensions (5.5" × 4.5" × 3.5") allow integration into space-constrained panel installations common on fishing vessels, superyachts, and expedition boats.

This unit is specified for marine DC and AC system integrators, vessel electricians, and boat owners building or upgrading electrical panels. Paneltronics components are industry-standard in commercial fishing, sailing, and trawler operations where reliable shore power management is essential. The double-pole design ensures simultaneous disconnection of both power legs during fault conditions, meeting marine electrical safety standards. Part number 9982316B (UPC 602290500439) is the direct replacement specification across multiple Paneltronics panel models.
