Equip your electrical system with reliable protection using the Newmar 30 Amp Single Pole Breaker featuring a sleek black throw handle. Designed for demanding environments like marine vessels, RVs, and off-grid setups, this breaker delivers precise circuit safeguarding without compromising on safety or performance. Its trip-free mechanism ensures consistent operation, preventing accidental resets under fault conditions and extending the life of your wiring and appliances.
Crafted to withstand vibrations, moisture, and temperature swings common in boating or mobile applications, this breaker combines durability with precision engineering. The magnetic-hydraulic trip mechanism responds swiftly to overloads and short circuits, minimizing downtime and potential damage. With #10 screw terminals on the rear, wiring is straightforward and secure, supporting clean installations in tight spaces.
This versatile breaker slots perfectly into Newmar electrical panels while fitting most competing brands, making it a smart upgrade or replacement choice. Whether refreshing an older marine distribution board or building a custom RV setup, its standard form factor ensures hassle-free integration. Note that for higher amp models beyond 30A, verify system voltage to match line-to-neutral or line-to-line configurations for optimal safety.
Boat owners trust it to protect inverters, battery chargers, and lighting circuits from surges caused by choppy waters or engine starts. RV enthusiasts appreciate its role in safeguarding AC units, microwaves, and converters during long road trips. Beyond protection, it contributes to system efficiency by allowing precise load management—pair it with monitoring tools to avoid nuisance trips from intermittent high draws like power tools or pumps.
Users report fewer false trips compared to thermal-only breakers, thanks to the hydraulic delay that differentiates safe inrush currents from true faults. This reliability translates to peace of mind, reducing troubleshooting time and repair costs over years of service.
Regular checks—every six months—keep it performing: inspect for corrosion, ensure free toggle movement, and confirm trip/reset functionality.
It's rated for up to 65 VDC or 277 VAC at 30 amps, making it suitable for a wide range of low- to medium-voltage AC and DC applications in marine and RV systems.
Yes, it's UL recognized, CSA listed for both AC and DC, and meets USCG requirements, ensuring compliance in commercial marine and recreational use.
Absolutely—it matches standard panel footprints from Newmar and most other brands, simplifying replacements or expansions.
Single pole protects one circuit leg, ideal for 120V loads; double pole handles two legs for 240V appliances, offering ganged operation for balanced protection.
The magnetic-hydraulic "trip-free" design uses magnetism for instant short-circuit response and hydraulics for timed overload protection, preventing manual override during faults.
Options include red, white, or black toggle handles, allowing customization for visibility or panel aesthetics.
Mounting screws are not provided; source them separately to match your panel's specs for a secure fit.
Perfect for safeguarding pumps, lights, chargers, and small appliances; its 30A capacity handles moderate loads like coffee makers or fans reliably.
All circuit breakers offered by NEWMAR are UL recognized and CSA listed for AC and DC
systems and meet USCG requirements as a qualified circuit protection device.
