Applications

Used for battery isolation in off-grid solar power systems, and for battery cut-off in motorhomes, caravans and boats. It also serves as emergency isolation for battery banks in vehicle and marine installations.

Installation and safety notes

Fit in series with the battery positive or negative conductor. DC battery circuits carry dangerous voltages and high fault currents, so wiring should be carried out by a qualified electrician with correctly sized cable and fusing.
