4-pole self-reset Circuit breaker , 40A 30 mA, class "A", for protection against isolation/bypass problems in homes, industries and the service sector. Compact Circuit breaker associated with an intelligent reconnection motor, which allows safe reconnection of the associated differential switch.

After a disconnection due to a differential trip, the reset attempt is made. The equipment makes up to a maximum of 3 attempts at time intervals. Once these attempts are exceeded, it is considered that there is an electrical problem and does not try again.

The equipment consists of two LED indicators, a protection cover for the reset system and a front switch to select the operating mode: manual as if it were a standard differential where reconnection must be done manually, or in automatic reconnection mode. It has a hole to pass a seal or padlock to block access to the differential and any attempt at manual reconnection.


This type of element is specially designed for any electrical installation where a full guarantee of service continuity is necessary in the event of unforeseen situations that may cause differential trips for reasons other than electrical insulation.

  • Housing sector: refrigerators, alarm systems, garage doors...
  • Services sector: air conditioning systems, cold rooms, lighting, SAIS....
  • Industrial sector: control of critical production processes

These differentials are electromagnetic in operation, which allows the safety function not to be lost in the event of supply voltage variations or loss of the neutral conductor; The differential trip only occurs with the bypass in the active phase.
