Description

Applications

• Boats

The M-750 Series 36V 310A Dual-Battery Selector &

Master Disconnect Switch is ideal for boats, emergency

vehicles, buses, heavy trucks, and RVs that use one

battery for starting the engine and another battery to

power auxiliary loads.

• Emergency Vehicles

• HeavyTrucks

• Buses

• RVs

This automotive and marine battery selector switch has

single-pole, triple-throw (SP3T) circuitry, which gives you

four options: batteries OFF, battery 1 ON, battery 2 ON, or

both batteries ON simultaneously.

Features and Beneﬁts

• 500A intermittent current at 12V dc for up to 5 minutes

and 310A maximum continuous current

• Single-pole, triple-throw (SP3T) switch allows you to use

one of two batteries or both batteries at the same time,

which enables maximum starting power

The battery cutoff position ensures reliable battery

disconnection to protect against electrical ﬁre, tampering

or theft, and battery drain, while the selector switch

positions allow for maximum starting power and backup

starting power during emergencies.

• Functions either with alternators or generators

• 3/8"-24 copper studs are solidly machined to the contact

plates

• High-performance rubber O-ring keeps water, dust, and

contaminants out
