Earth Leakage Relay
Puneet Industrial Controls is a leading manufacturer of electronic control relays. The company has introduced its new outlook Earth Leakage Relay. This is a fully solid state electronic device for protection of electrical machines and equipment against insulation breakdown and earth leakage.

Whenever there is an earth leakage, the CBCT senses it and an electromagnetic relay is operated in case the leakage current exceeds the set value. Two potential free changeover contacts of the relay are provided for customer usage at the terminals for external connections. Light emitting diodes (LEDs) are provided on top of the unit to indicate voltage supply and relay On status. The current setting is from 3 mA (current display can be provided against requirement).
