ELR-3B Earth Leakage Relays WITHOUT BUILT-IN Toroidal Transformer

RELAY WITH ADJUSTABLE DELAY TIME AND SENSITIVITY

  • Type B earth leakage relay. Suitable for Direct current (DC), pulsating current, and alternating current (AC) up to 1000 Hz.
  • Electronic relays with adjustable time delay and sensitivity.
  • Immune to external disturbances.
  • To be used with CTB toroidal transformers.
  • Modular DIN rail mounting. 3 modules.
  • Sealable front cover.
  • Fail-safe function (settable).

For this type of differential, using CTB toroidal transformers increases safety by guaranteeing the continuity of operations and minimizing risks:
