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.
- Ensures that the breaker closes only once for one close command from the control panel
- Prevents multiple circuit breaker closure
- Thermal sensing and shutdown
- Designed for long service life
- Charging current selection available on request
- Wide range of SMPS and Linear Battery Chargers available
- Designed for continuous duty application
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.
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.
Features & Benefits:
- Sensing by electronic circuit
- Low supervision current
- Immune to breaker operation
- Continuous monitoring
