DELTA - RESIDUAL CURRENT DEVICE

Maximum system security

DELTA relays are ideal for use in the industrial and service sectors, in public lighting and in the construction of automatic machinery. They comply with the protection standards dictated by the IEC EN 60947-2 Annex B and M Class A standard, thus compatible with pulsating currents (therefore with continuous components).
The DELTA range of modular and built-in residual current relays, combined with Del and Del A toroidal transformers (which can be opened), has the objective of protecting people and things, while ensuring continuity of service for the plants.

Relè Differenziali Delta - Caratteristiche - Controllo

Permanent connection control

An important feature of the Delta series is the permanent connection control of circuit between residual current relay and C.T.: by detecting of any anomaly in the connection between C.T. and E.L.R., the protection automatically intervenes, without waiting for the periodic check to carry out by test push button.

Relè Differenziali Delta - Caratteristiche - Regolazioni

Simple and immediate adjustments

The settings of the times and of the tripping currents occur for most of the Delta devices, through the practical dip-switches or rotary selectors on the front of the differential relay and therefore easily accessible. The Δt tripping time adjustment makes this series ideal for the creation of selective protection systems; adjustment in IΔn current makes it possible to protect people and property against undesired or dangerous dispersions.

Relè Differenziali Delta - Caratteristiche - Soluzioni

Solution for panel and DIN35 rail

The range is very rich and consists of luminaires with modularity of 2 or 4 DIN35 modules or in recessed version for panel installation.

Relè Differenziali Delta - Caratteristiche - Versione

Version with harmonic filter

With the evolution of system requirements and the introduction into the systems of devices fitted with power electronics, the F models have been created with harmonic filter for systems that are subject to considerable disruption.
