Robust Protection for Your Electrical Systems

Engineered for demanding environments like marine vessels and recreational vehicles, the Newmar 20 Amp Double Pole Breaker with Black Throw delivers dependable circuit protection. Its magnetic-hydraulic trip-free design ensures instant response to overloads and short circuits, preventing damage without the nuisance tripping common in basic thermal breakers. Whether you're powering navigation gear, appliances, or lighting, this breaker safeguards your setup with precision.

Core Specifications and Build Quality

Amperage and Poles: 20A double pole configuration, ideal for handling two hot legs simultaneously in 240V or split-phase systems.
Voltage Ratings: Up to 65VDC or 277VAC for 20A models, supporting a wide range of AC and DC applications.
Mechanism: Advanced magnetic-hydraulic actuation for reliable, repeatable performance under vibration and temperature swings.
Terminals: Secure #10 screw connections on the rear for straightforward wiring with standard marine-grade cables.
Handle: Distinctive black throw toggle for quick visual status checks and intuitive operation.

This breaker stands out for its trip-free feature—once tripped, it won't reset until the fault clears, adding an extra layer of safety during troubleshooting.

Seamless Fit and Versatile Applications

Designed to slot perfectly into Newmar electrical panels, it also works with panels from leading brands thanks to standardized mounting dimensions. In marine settings, it meets USCG standards for qualified protection devices, while UL recognition and CSA listing confirm its reliability across North American installations.

Upgrade your RV's power distribution or boat's switchboard with confidence. The double pole setup excels at protecting branch circuits for air conditioners, water heaters, or inverters, minimizing downtime and extending equipment life.

Effortless Installation for DIY Enthusiasts

Drop it into your panel's designated slot—mounting screws sold separately ensure you use the right size for your setup. Strip your wires to expose 1/2 inch of conductor, secure them under the #10 screws, and torque to spec (typically 20-25 in-lbs). Always de-energize the system first and double-check polarity on DC applications. Pro tip: Label circuits post-install for faster diagnostics down the line.

Quick Troubleshooting Guide

Visually inspect for a tripped black handle (down position).
Address the overload cause—loose connections or faulty appliances.
Firmly reset by flipping up; if it immediately trips again, isolate the fault.

Part of a Reliable Breaker Family

Newmar's lineup offers flexibility with single pole options from 5-50A and double pole up to 50A. Choose red, white, or black handles to match your panel aesthetics. Note for high-amp models (above 30A): They're suited for 230V line-to-line systems (115V leg-to-neutral) but verify against line-to-neutral setups to avoid mismatches.

Frequently Asked Questions

What makes the magnetic-hydraulic mechanism better for marine and RV use?

Unlike simple thermal breakers, the magnetic-hydraulic design combines instant magnetic response for shorts with hydraulic damping for overloads. This resists nuisance trips from vibrations or motors starting, common in boats and RVs.

Is this 20A double pole breaker suitable for both AC and DC systems?

Yes, it's rated for up to 65VDC or 277VAC at 20A, making it versatile for hybrid setups like solar-equipped RVs or onboard generators.

Does it fit panels from other manufacturers?

Absolutely—standard dimensions ensure compatibility with most industry-standard panels beyond Newmar, simplifying replacements.

What safety certifications does this breaker carry?

UL recognized, CSA listed for AC/DC, and meets USCG requirements, providing peace of mind for commercial and recreational marine applications.

Are mounting screws included with the breaker?

Mounting screws are not provided; source them separately based on your panel's thickness and thread size for a secure fit.

How do I know if it's tripped, and can it be manually held in the on position?

The black handle drops to the off position when tripped. It's trip-free, meaning it cannot be held on during a fault— a critical safety feature.

What amp values are available in double pole configuration?

Double pole options include 15A, 20A, 30A, and 50A, with voltage ratings varying by amperage for optimal matching to your loads.

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.
