Current Protection Relay
The main earth fault protection relays in distributions systems, power stations & large manufacturing / processing plants can fail to detect a high impedance break down to earth causing hazard to human life & potential damage to plant & equipment. In these & other situations demanding extra sensitive earth fault protection, using solid state techniques, can be applied to detect earth currents down to 0.5% of the CT nominal current.

Timer, Delay-Off, 4 Pole
TDE4N relay
Plug-in electronic industrial timer relay with four change-over contacts. When the relay is de energized there is a delay on drop-out without any auxiliary power supply. The delay time is adjustable with a lockable knob. The relay can also be supplied with a fixed time delay (no knob).The relay is equipped with a LED which indicates the presence of energizing voltage. Standard equipped with back EMF suppression. Optionally equipped with magnetic arc blow-out for high breaking capacity and long contact life.
