Newmar 5ASB Single Pole Breaker W/ Black Throw

Discover Reliable Protection with the Newmar 5ASB Single Pole Breaker

Reliability is everything when it comes to electrical systems in demanding environments like marine vessels, RVs, or off-grid setups. The Newmar 5ASB single pole breaker with black throw stands out as a robust solution, delivering precise circuit protection that keeps your power flowing safely. Unlike basic fuses that need constant replacement, this breaker trips reliably under overload and resets effortlessly, saving you time and hassle on the water or road.

Crafted for seamless integration, it fits effortlessly into Newmar electrical panels and most competing brands, making upgrades straightforward without major rewiring. Its magnetic-hydraulic trip-free mechanism responds instantly to faults—magnetic for short circuits, hydraulic for sustained overloads—ensuring equipment stays protected without nuisance tripping from temporary surges.

Key Features That Set It Apart

• Proven Safety Certifications: UL recognized and CSA listed for both AC and DC applications, plus meets stringent USCG standards—ideal for marine pros who demand compliance without compromise.
• Versatile Voltage Handling: Handles 5-30 amp models up to 65 VDC or 277 VAC; 40-50 amp up to 32 VDC or 120 VAC, covering a wide range of systems from 12V batteries to 240V shore power.
• Secure Connections: Rear #10 screw terminals for solid, vibration-resistant wiring that holds up in rough seas or bumpy trails.
• Customizable Style: Black throw option blends discreetly with modern panels; other colors available for clear status indication.
• Panel-Ready Design: Snap-in fit for quick installs, though you'll want to grab mounting screws separately for a rock-solid hold.

This isn't just a breaker—it's engineered for longevity, with a trip-free design that prevents manual override hazards during faults, a critical feature in safety-focused applications.

Perfect Fit for Your Setup

Whether safeguarding inverters, battery banks, lighting circuits, or appliances, the 5ASB excels in single-pole configurations (5A to 50A ratings). Need double-pole protection for 240V loads? Pair it with a matching unit for balanced safeguarding. It's a go-to for boaters retrofitting old panels, RV enthusiasts expanding solar arrays, or anyone prioritizing fault-tolerant power distribution.

Real-World Applications

• Marine: Protects navigation gear and pumps from shorts amid saltwater exposure.
• RV/Overland: Handles generator feeds and AC units during long hauls.
• Off-Grid/Solar: Guards charge controllers and high-draw inverters reliably.

Installation Tips for Peak Performance

Getting it right from the start maximizes safety and uptime. Start by powering down your system completely. Snap the breaker into your panel's slot—its standard footprint ensures compatibility. Secure with #10-32 mounting screws (sourced separately for your panel thickness). Connect wires to the rear terminals: positive/line to the top, load to the bottom, torquing to spec for corrosion resistance in humid environments.

Pro Tip: Label circuits clearly and test under load post-install. In AC setups, remember the rating note—over-30A models shine in 230V line-to-line (115V leg-neutral) but check for direct 230V neutral-line use to stay within specs.

Why Choose Newmar 5ASB Over Standard Breakers?

In a sea of generic protectors, the 5ASB delivers superior trip curves tailored for real loads—no weak thermal responses that fail under inrush currents from motors. It's built tougher for vibration-heavy use, with a sleek black throw that resists fading. Users rave about its reset reliability after surges, cutting downtime versus hunting for spares. For systems where failure isn't an option, this breaker invests in peace of mind.
