ELPR - Smart & Smart+ \ Product Features: ^ Easy operation ^ CBCT connection fault detection ^ Programmable parameter through potentiometer ^ DIP switch for settings (Smart version only)+ ELPR - SMART & SMART+ Cj \ sifam tinsley ELPR Sifam Tinsley ELPR is earth leakage relay (ELR), a protection device to be used in electrical installations against electric shock and / or damage to equipment caused by punctured or weak insulations or contact to live parts. Instrument operates by monitoring the earth leakage current through CBCT and disconnecting the circuit in case of hazardous levels of earth...

ELPR - SMART & SMART+ Remote Reset: Two contacts are provided at terminal block, can be used for remote reset operation, These contact function are similar to reset key operation 1. Bar graph - Measured leakage current in terms of percentage of set leakage current (In), and indicated by 4 LED’s as per 30%, 45%, 60%, 75% of set value. 2. PON - Indicates device is powered on and working. Additionally it shows CBCT fault condition by blinking 3. Trip - Indicates relay fault state. 1. PON LED ON - Device is powered on and functioning 2. PON LED Blinking - CBCT Open detected 3. Trip LED ON - Relay...
