The MT003 is a voltage sensitive relay isolator designed for dual battery layouts running on 12V DC. Rated at 140A continuous with a 160A intermittent allowance, it handles the charge and load current of a typical start-plus-auxiliary arrangement without requiring the driver or skipper to remember a manual switch.
The relay monitors system voltage and links the two batteries once charging begins, then separates them again when the engine stops and voltage falls away. The result is a simple arrangement that tops up the auxiliary bank while driving or motoring, yet keeps the starting battery isolated so a fridge, winch or inverter cannot flatten it overnight.
The body is moulded in nylon — light, tough and naturally resistant to moisture, fuel splash and the constant vibration of an engine bay. With no moving parts to service and no manual knob to forget, the unit suits owners who want dual-battery management to look after itself.

Plan the layout before drilling anything — the relay sits between the two positive feeds and shares a common ground:
Practical tip: for a winch or inverter fed from the auxiliary bank, size the cable for the peak draw rather than the 140A average — the 160A intermittent allowance covers short surges, not continuous heavy loads.
Not necessarily — this is an automatic VSR unit. Many owners keep a manual master switch for isolation during service and add the relay for day-to-day charge management.
The unit is built for 12V DC systems. For 24V layouts, ask us about alternative models before ordering.
The relay simply stays open until charging voltage rises. Fit a suitable fuse or breaker on the auxiliary feed so a fault cannot draw current through the relay.
Yes — minimum order is 1 piece, and samples are welcome at any time.
Yes. We work from customer samples and technical drawings, including the tooling a new design requires.
