Newmar SS Switch 15 Transfer Switch 15KW

Imagine cruising on your boat, powering up appliances with confidence, knowing your electrical system is protected from overloads or conflicts between shore power, your generator, and inverter. The Newmar SS Switch 15 steps in as your reliable guardian, seamlessly switching between AC sources without the risks of simultaneous power feeds that could fry circuits or spark hazards.

Why Boaters Trust the Newmar SS Switch 15 for Flawless Power Management

Designed specifically for marine environments, this 15KW transfer switch handles the demands of onboard living—from running air conditioning during hot anchorages to charging batteries via inverter. Unlike basic toggles, it features a robust build that stands up to saltwater corrosion, vibrations from rough seas, and constant use. Boat owners rave about its smooth operation, which prevents those frustrating power interruptions that ruin a perfect day on the water.

Standout Features That Set It Apart

• Compact Escutcheon Plate: Sleek design with clearly engraved positions (Shore, Generator, Inverter) for intuitive use, even in low-light cockpits. Fits panels up to 1/4-inch thick without modifications.
• Heavy-Duty Contacts: Engineered for high amperage loads up to 15KW, ensuring minimal voltage drop and reliable performance under full load.
• Positive Step Cam Mechanism: Delivers precise, low-resistance connections that eliminate arcing and extend switch life—critical for remote voyages where repairs aren't an option.
• Global Certifications: UL, CSA, and VDE approvals mean it meets stringent safety standards across regions, giving peace of mind for international cruisers.

Real-World Benefits for Your Vessel

Switching sources manually keeps you in control, avoiding automatic transfer switch failures common in automated systems. It's ideal for setups with a 50A shore inlet alongside a 5-7KW generator and inverter combo. Users report fewer tripped breakers and extended inverter battery life, as it prevents backfeeding that stresses components. Pair it with your battery monitor for a complete power oversight system, optimizing runtime during off-grid adventures.

Effortless Installation and Maintenance

Mounting is straightforward: Secure the escutcheon, wire to your AC bus (observing color codes and torque specs for marine-grade terminals), and test sequences. No special tools needed beyond basics. For longevity, inspect contacts annually— a quick wipe with electrical cleaner keeps it humming. It's compatible with most 120/240V marine panels, from sailboats to motor yachts.

Safety First: How It Protects Your Boat and Crew

By design, it ensures only one source energizes your circuits at a time, dodging phase mismatches or ground faults that plague multi-source setups. This proactive safeguard reduces fire risks and equipment damage, letting you focus on the horizon rather than wiring woes.
