ELR1.0 is a compact design based on the latest digital technology. It monitors the earth current with a core balance current transformer (CBCT). By monitoring it detects and protects power systems from Earth leakage faults. In the event of an earth leakage, ELR will trip the contactor, etc., to isolate the load. LEDs are provided on Top of the unit to indicate earth leakage fault and alarm indication.

The C&S earth leakage relays provide safety against electric shocks and fires, as well as system reliability by preventing damage to equipment. Fast fault detection and isolation, protection of expensive equipment like transformers and motors, and compliance with safety regulations are key advantages.
  • Leakage protection for Feeders, Motors, Generators, Transformers etc.
  • Leakage protection for LT control panels & switch boards
  • Protections for mining and control engineering
  • Protections for expensive equipment in hazardous, sensitive environments like Oil refineries, cement plants, chemical plants, steel plants, pulp industries and general electrical distribution units
