Newmar 50 Amp Double Pole Breaker W/ Black Throw
Newmar 50 Amp Double Pole Breaker W/ Black Throw — Product description
Reliable Protection for Demanding Electrical Systems
When powering high-demand setups like marine vessels, RVs, or off-grid installations, you need circuit breakers that deliver unwavering performance under pressure. The Newmar 50 Amp Double Pole Breaker with Black Throw stands out with its robust magnetic-hydraulic trip-free mechanism, ensuring instant response to overloads or faults without the risk of manual override failures. This design resets automatically after cooling, minimizing downtime and enhancing safety in critical environments.
Engineered for Versatility and Compliance
- UL recognized and CSA listed for both AC and DC applications, plus meets stringent USCG standards for marine use.
- Rated for 50 amps at up to 32 VDC or 120 VAC, ideal for handling heavy loads like inverters, air conditioners, or propulsion systems.
- Universal fit: Seamlessly integrates into Newmar electrical panels and most competing brands, thanks to standard mounting dimensions.
- Secure #10 screw terminals on the rear simplify wiring connections, supporting robust, vibration-resistant installations.
Note for high-voltage setups: While perfect for 230 VAC line-to-line systems (common 115 VAC leg-to-neutral), confirm specs for pure 230 VAC line-to-neutral to avoid mismatches.
Why This Breaker Excels in Real-World Applications
Unlike basic thermal breakers, the magnetic-hydraulic action provides precise, nuisance-free tripping—protecting sensitive electronics from surges while allowing brief inrush currents from motors or chargers. Boat owners appreciate its black throw handle for discreet panel aesthetics, blending with custom dashboards. RV enthusiasts rely on it for dual-pole protection across hot and neutral lines, preventing ground faults that could spark hazards.
Pro Installation Tips for Peak Performance
Secure mounting requires separate screws—opt for stainless steel in marine settings to combat corrosion. Torque terminals to manufacturer specs (typically 20-25 in-lbs) for optimal contact without stripping. Always pair with appropriately sized wire (e.g., 6 AWG for 50A runs) and fuses upstream for layered defense. Test post-install by simulating loads to verify trip thresholds.
"Switched to Newmar breakers after repeated trips on generics—flawless under 5kW inverter loads during extended anchoring."

Perfect Fit for Marine, RV, and Solar Systems
Double-pole configuration interrupts both legs simultaneously, essential for 120/240V split-phase or DC battery banks. Compatible with popular panels from Blue Sea, Victron, and Magnatek. In solar arrays, it safeguards charge controllers from reverse currents; in yachts, it guards galley appliances from voltage spikes.
