Arteche trip circuit supervision relays monitor trip coil circuit in open/close states and during circuit breaker operation. TCS relays are used for DC supervision via LOR trip coil, generating an alarm and avoiding open/close commands under faulty conditions or when breaker tripping mechanism is not ready to operate.

With references for single pole and 3 pole and a wide range of voltages, VDF / VDJ trip circuit supervision relays performs monitoring functions over circuits, fuses, and MCBs involved in the control power supply circuit of switchgears and other critical control circuits.
