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.
