Electronic Relays

Various relays to suit requirement

Anti Pumping Relay (APR)

It prevents multiple circuit breaker closure.

If the close command remains in the pressed condition,there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker.

Anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.

Electronic Earth Fault Relay

Earth fault/ground fault protection relay, is an Electronic trip unit, designed to protect the electrical installation in case of faults or leakage currents beyond a preset level. The trip delay is adjustable. The potential free contact output of this unit can be wired in to the user system for interlock & protection.

Earth Fault Relay

Features & Benefits

  • Auxiliary Power Supply , 50 Hz / 60Hz, 110 Volts , 230 Volts or 415 Volts (nominal)
  • External Current Input Signal thru input CT , 1Amp or 5 Amps, as Full-Scale Input
  • Sensitivity Setting, 10% to 100%  (Field Settable)
  • Trip Time Delay Setting, 100milli-Seconds to 1 Seconds (Field Settable)

Trip Circuit Supervision Relay

Trip Circuit Supervision Relay (TCSR) monitors the healthiness of the trip circuit of breaker.Basically the circuit of breaker. Basically the circuit drives a small current through the breaker trip coil and monitors it continuously.if there is any failure in the trip coil circuit, the relay will sense and operate its output contacts.

Trip Circuit Supervision Relay

Features & Benefits

  • Sensing by electronic circuit
  • Low supervision current
  • Immune to breaker operation
  • Continuous monitoring
