Battery Disconnect Switch 12V-48V Master 275A High Current Car Marine RV

Description:

Universal 12V-48V High-Current Isolation:
Compatible with cars, boats, RVs, and solar systems, this 275A battery switch handles 12-48V DC power systems. Safely disconnects primary batteries during maintenance or storage, preventing parasitic drain and electrical fires across automotive/marine applications with rugged vibration-proof construction.

275A Continuous Load Capacity:
Heavy-duty copper contacts support 275A continuous current (300A surge) for winches, inverters, or dual-battery setups. Thermal-cutoff protection prevents overheating during high-demand operations, exceeding SAE J560 standards for starter circuits and auxiliary power systems.

Corrosion-Resistant PC/ABS Housing:
Industrial-grade polymer blend resists saltwater, fuels, and UV degradation. IP65-rated enclosure (-40°C to 85°C operational range) ensures reliability in engine bays, bilge compartments, or off-road environments where moisture and impacts are common.

Manual On/Off Control and Safety Lock:
Key-operated rotary switch enables secure power cutoff with visual status indicators. Includes padlock provision to prevent unauthorized reactivation critical for marine safety compliance (ABYC E-11) and theft prevention.

Compact 8x8x4cm Design and Easy Integration:
Space-saving cube form factor installs in minutes with M8 terminals (accepts 2/0-4 AWG wires). Rated for 1000+ mechanical cycles with brass contacts maintaining <0.5mΩ resistance throughout lifespan.
