C.E.DI.T. Earth Fault Indicator - EFI.02

OVERVIEW:

• Designed to be installed on MV cables up to 33kV (underground, switchgear, cells, etc.).
• Local earth fault signalling by means of flashing LED.
• A single level of trip current (current value can be customer defined).
• Reset modes: time-delay, 230Vac mains voltage and pushbutton reset (time-delay value can be customer defined).
• Single fault-delay value for transient cancellation (delay value can be customer defined).
• Correct operation (test) can be checked pressing the pushbutton on the front.
• Self-powered by the internal lithium battery with 10 years lifetime and over 2500 flashing hours.
• The battery can be easily replaced with lithium 3,6V - ½ AA type (no soldering or tools required).
• Electronic module enclosed in IP65 box linked to the external current transformer CBCT.
• Split-type resin current transformer CBCT ring–type, composed of two halves that can be installed without MV cables disconnection and held together by metallic screw tie.
