Specification for earth leakage relay:
- Description: Used for continuous surveillance of the earth leakage current which causes generation of heat & progressive failure of insulation, when current value moves out from the desired zone the relay energizes to give an alarm or trip a circuit.
- Input Current: CBCT [Current Balance Current Transformer] X2 continuously, X10 for 3 sec. As per BS6253.
- Setting of trip Point: 30,100,300,500 mA, 1, 3, 5, 10, 20, 30Amp. Settable.
- Delay Time: 0, 0.06, 0.15, 0.25, 0.5, 0.8, 1, 2.5, 5, 10 sec settable.
- Alarm Relay Output: 50% of range 1C/O [Contact rating 5A].
Specification for digital frequency relay:
- Description: Digital frequency relay Single Set Point [High side], Panel.
- Time Delay: .1 sec to 9.9 sec.
Specifications for voltage relay three phase:
- Description: Three Phase Voltage relay for OV/UV/PR/NL, Rail Mounting.
- Input Voltage: 415 VAC 3 Phase 4 Wire.
- Under Voltage: -75% to 100%.
- Over Voltage: 100% to 125%.
