Newmar SS Switch 7.5 Inv 7.5KW AC SELECTOR SWITCH 023-2206-0

The Newmar SS Switch 7.5 Inv 7.5KW AC Selector Switch 023-2206-0 is the backbone of reliable onboard power management for serious cruisers and liveaboards who demand seamless AC source selection. Whether you're docked shoreside, running a generator, or managing dual power inputs, this intelligent selector switch routes 7.5 kilowatts of AC capacity between independent sources without interruption. Built by Newmar—a trusted name in marine power systems—this component eliminates manual breaker switching and the risk of accidental dual-source backfeeding that can damage sensitive electronics or create dangerous electrical faults on the water.

The 7.5KW capacity makes this switch ideal for vessels with substantial AC loads: air conditioning, electric stoves, water heaters, and high-amperage battery chargers all running simultaneously. The inverter-rated design (indicated by "Inv" in the model designation) means it's fully compatible with modern marine inverters and inverter/chargers, allowing you to switch between generator, inverter, and shore power without power loss or electrical noise that degrades navigation systems. The solid-state switching architecture eliminates mechanical relay chatter and provides cleaner transitions than older rotary or manual selectors—critical when you're underway and every millisecond of uninterrupted power counts for autopilot, radar, and other mission-critical systems.

This selector is essential for any cruising or liveaboard vessel with multiple AC power sources: a genset, shore power pedestal, or rooftop solar + inverter combination. Installation typically occurs in the main AC distribution panel and requires proper breaker coordination upstream; consult your vessel's electrical schematic or have a marine electrician verify compatibility with your specific inverter model and circuit configuration. At 4 lbs, it integrates cleanly into existing panel layouts without requiring structural reinforcement. For boats operating in remote anchorages or extended offshore passages where reliable power switching prevents equipment damage and system downtime, the Newmar SS Switch 7.5 Inv delivers the dependability that separates a well-engineered electrical system from a marginal one.
