Newmar 50 Amp Single Pole Breaker W/ Black Throw

The Newmar 50 Amp Single Pole Breaker W/ Black Throw is a marine-grade electrical protection device designed for RV, boat, and off-grid power systems requiring reliable circuit isolation and load protection. This single-pole breaker fits seamlessly into Newmar electrical panels and remains compatible with most other premium panel brands, making it an ideal choice for system upgrades, replacements, or new installations. Built to meet demanding maritime and mobile power standards, this breaker delivers the dependable overcurrent protection that demanding electrical systems require.

All Newmar circuit breakers are UL recognized and CSA listed for both AC and DC electrical systems, meeting rigorous USCG requirements as a qualified circuit protection device. The 50-amp rating provides substantial capacity for high-load applications such as main battery banks, inverter circuits, or auxiliary power distribution in marine and RV environments. The black throw handle offers clear visual status indication and ergonomic operation, allowing users to quickly identify whether the breaker is in the on or off position even in low-light conditions common aboard vessels and in remote installations.

This single-pole configuration suits applications where circuit isolation is required for specific branches—such as generator circuits, battery charger inputs, or dedicated appliance feeds—rather than three-phase balanced loads. Technicians, marine electricians, and RV system integrators depend on Newmar breakers for their proven longevity and predictable trip characteristics under fault conditions. Installation is straightforward into compatible Newmar panels and most industry-standard DIN-rail or panel-mount enclosures, making replacement and system expansion practical for both professional service and field upgrades.
