Double-Pole Master Disconnect Switch - TR Series

Littelfuse's TR series dual-pole master disconnect switch's primary function is to cut all battery power from vehicle electrical systems for applications needing switching of two circuits. It is ideal for commercial vehicles built to handle 500 A continuous current for each of the two circuits (using 2 x 4/0 input and 2 x 4/0 output cables). It can be used to switch two vehicle voltage circuits simultaneously (24 V and 12 V) or disconnect a battery or multiple batteries in either the positive or the negative line. It has an added harsh-environment protection like ingress IP67 and IP69K, which means that the switch can be mounted in exposed locations on the vehicle.

Features

• 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
• Direct lockout/tagout capability in on or off position with padlock or hasp
• 500 A per circuit with 2 x 4/0 input and 2 x 4/0 output cables
• 350 A per circuit with 1 x 4/0 input and 1 x 4/0 output cables
