Description

The TBS 12V500A isolation relay can be used to switch circuits with high loads. At 12 volts, the relay can handle a continuous current of 500 amps. For a short-term continuous load of up to one minute, the relay can also withstand 1,000 amps. The peak starting current is 1,600 amps.

The relay can be controlled either via a button on the relay or via an optional remote control. The 40-centimeter-long control cables can be extended up to 15 meters.

The TBS 12V500A cut-off relay is ideal for use with the Nomia 12V100AH, Nomia 12V160AH, Nomia 12V210AH, and Nomia 12V340AH Super B battery types. For normal use in a motorhome or caravan, the use of a relay or protection circuit is mandatory; otherwise, the warranty and guarantee will be void. This relay allows you to fully utilize the performance of Nomia batteries. The TBS 12V500A cut-off relay ensures that the circuit is immediately interrupted in the event of battery problems. To do this, simply connect the control lines to the battery.

For less power-hungry applications up to 190 amps, a cheaper, bistable relay is available in our shop.
