Current Alarm Trip Unit
Current Alarm Trip Unit
Lectrotek Systems Pvt Ltd offers a Current Alarm Trip Unit, Model INDEL-CTR. This is a direct current controller for AC (alternating current) circuits and loads and requires no transducers for its operation. It accepts direct current inputs up to 5 A and over that from CTs (1 A or 5 A). The CT inputs are site selectable. Readout of the current input is also direct and the range is programmable by user outputs are in terms of alarm and trip relays which are triggered by alarm/trip setpoints programmed by user. Relays are potential-free type with changeover (1 NO+1 NC) contacts, rated for 7 A, 240 V AC resistive loads. Relays may be made to operate on failsafe High or Low.
