Cut all battery power to vehicle electrical systems with the TR Series 32V 500A 2-Pole Waterproof Master Battery Disconnect Switch. The dual-pole, single-throw (DPST) switch works in heavy-duty truck, construction, emergency vehicle, bus and transit, military, and agricultural applications requiring the switching of two circuits or both positive and negative.

You can feel confident mounting this master battery disconnect switch in exposed locations thanks to its IP67 and IPX9K waterproof and dustproof ratings as well as its high shock and vibration tolerance.

The dual battery disconnect switch can be used to disconnect one or two batteries in either the positive or negative line, and it can be used to switch two vehicle voltage circuits simultaneously (24V and 12V).

Integrated lock-out/tag-out (LOTO) capability in either the on or off position using a padlock or hasp (not included) helps ensure personnel safety and vehicle security.
