Differential relay type A 0.03 A DIN rail

Type A differential relay with a fixed sensitivity of 0.03 A, designed for protection against residual currents in electrical installations by DIN rail mounting. It acts instantaneously against current leaks, compatible with open and closed type A toroidal transformers of the Vigirex TOA, Vigirex A and Vigirex L ranges. It works with power voltage 220-240 V AC, 50/60 Hz, and supports voltage peaks up to 8 kV. Operating in temperature ranges from -35 to 70 °C, with IP40 protection degree on the front face.
