Earth leakage relay
Delta D4-I is the new 4 module housing earth leakage relay for use in public lighting systems, traffic lights and unattended equipments. It can guarantee the differential protection and at the same time to avoid the permanent cutting out of the systems in the cases of transitory breakdowns (example overstrains induced by a lightning). Although this relay is for sinusoidal (AC type) or pulsating residual current with DC component (A type) waveforms, in compliance with IEC60947-2 VIII edition 2007 (annex B and M).

Earth leakage relay
IME's flush mounting 96x96mm earth leakage relay range gets enriched by a new model, the Delta 96-F, just suitable for heavy industrial applications with distorted current waveforms (inverters, variable speed drivers, rectifiers, frequency regulators). It mustn't be used to protect people (automatic cut-out). The minimun set threshold is 50mA. Available also in 72x72mm flush mounting housing version (Delta 72-F).

ACCESSORIO |
 |
CT accessory
Purchasing code ATAP015 is a protection device for current transformers. Dangerous over voltages can be expected at the secondary terminals of current transformers, in case of disconnection of the load of the secondary circuit, ATAP015 auotomatically short circuits the secondary circuit while deactivates itself on the return of the normal operating conditions. It does not affect the CT performance.
