Newmar SS Switch 3.0 3KW Transfer Switch

Enhance Your Boat's Electrical Safety with Seamless AC Source Switching

Imagine cruising on open waters, powering your onboard systems effortlessly between shore power, a humming generator, or a quiet inverter—without a single worry about crossed circuits or electrical mishaps. For marine enthusiasts, managing multiple AC power sources is a daily reality, but it comes with risks. That's where a robust AC source selector switch steps in, acting as the vigilant guardian of your boat's electrical system.

This 3KW transfer switch is designed specifically for vessels equipped with onboard generators or inverters. It ensures only one power source feeds your circuits at a time, preventing potentially damaging backfeeds or hazardous overloads that could fry appliances, trip breakers, or worse, spark safety issues.

Key Features That Stand Out on the Water

• Compact and User-Friendly Design: Features a sleek escutcheon plate that's easy to mount and read, with clearly engraved positions for shore power, generator, or inverter—making quick switches intuitive even in rough seas.
• Heavy-Duty Performance: Built with rugged contacts that handle 3KW loads reliably, paired with a precision-engineered cam mechanism for snug, low-resistance connections that minimize voltage drops and heat buildup.
• Versatile Installation: Fits snugly into panels up to 1/4-inch thick, ideal for retrofits or custom dashboards without major modifications.
• Certified Reliability: Meets stringent UL, CSA, and VDE standards, giving you peace of mind in demanding marine environments where moisture, vibration, and salt air are constant challenges.

Unlike basic toggles, this switch's positive-step action delivers a satisfying "click" that confirms position, reducing user error during high-stress moments like anchoring at dusk or firing up the genny mid-voyage.

Real-World Applications for Boaters

Whether you're a weekend sailor docking at marinas with inconsistent shore power or a liveaboard relying on solar-fed inverters during extended off-grid adventures, this transfer switch simplifies power management. Picture transitioning from generator to inverter silently as you slip into a no-wake zone—no buzzing, no fuss.

It's particularly valuable for setups with sensitive electronics like navigation systems, refrigeration, or air conditioning that demand stable power. By isolating sources, it protects investments and keeps your vessel running smoothly, trip after trip.

Effortless Installation and Long-Term Maintenance

Setting it up is straightforward for DIY-savvy boaters or pros alike. Drill standard mounting holes, secure the escutcheon, wire your sources to clearly marked terminals, and test. The compact footprint saves valuable dash space, and its durable construction means minimal upkeep—just occasional visual checks for corrosion in salty conditions.

Pro tip: Pair it with proper fusing on each input to add an extra layer of protection against surges from generators or grid fluctuations. Over time, its low-wear contacts outlast cheaper alternatives, reducing replacement hassles.

Why This Switch Elevates Your Boating Experience

In the world of marine electrics, reliability isn't optional—it's essential. This 3KW model stands tall with its battle-tested engineering, ensuring your power transitions are as smooth as your favorite coastal run. Boaters rave about the confidence it instills, freeing them to focus on the horizon rather than wiring woes.
