    Littelfuse TR Dual-Pole Master Disconnect Switches
    TR Dual-Pole Master Disconnect Switches
    Littelfuse TR Dual-Pole Master Disconnect Switches cut all battery power from vehicle electrical systems with applications needing switching of two circuits or both positive and negative. Littelfuse TR Dual-Pole Master Disconnect Switches feature a 500A continuous current rating for each of the two circuits (using 2x 4/0 input and 2x 4/0 output cables). The TR series can be used to switch two-vehicle voltage circuits simultaneously (24V and 12V). These switches allow the user to disconnect a battery or multiple batteries in either the positive or the negative line. Ingress protection to IP67 and IP69K means that the switch can be mounted in exposed locations on the vehicle.
