880175 - TR Series

TR Series dual pole 500A Master Disconnect Switch cuts all battery power from vehicle electrical systems with applications needing switching of two circuits, or both positive and negative.

Ingress protection to IP67 and IP69K means that the switch can be mounted in exposed locations on the vehicle. Drop-in replacement for competitive Master Disconnect Switches, with higher vibration and shock capabilities. 500A continuous current rating for each of the two circuits (using 2 x 4/0 input and 2 x 4/0 output cables). Can be used to switch two vehicle voltage circuits simultaneously (24V and 12V). Disconnect a battery or multiple batteries, in either the positive or the negative line. Direct lockout/tagout capability in On or Off position, with padlock or hasp.
