Self-rearmable differential 2 poles 40A 30mA Class A immunized

Self-rearmable electrical differential switch, 40A 30 mA, category "A", 2 poles, for protection of people against insulation/derivation problems in installations or electrical elements. Specially recommended for use in live.

The automatic reset system will allow a reconnection in the face of an untimely firing of the same, not produced by a permanent current of derivation. The self-rearmable differential will perform automatic reconnection by successive time sequences, controlling the isolation conditions, so that it will not reconnect until the defect that caused the shot has disappeared. This maintains maximum safety and continuity of electrical service, avoiding unnecessary reconnection attempts.

This system is very useful in homes for sporadic use or where the loss of electric service can cause loss of food or in safety systems, sewage treatment plants, etc.

Applications: equipment specially designed to be installed in all installations where a full guarantee of continuity of service is needed in the face of unforeseen situations that cause differentials to be fired for reasons other than electrical insulation.

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

Using a front switch, it is possible to override the automatic reconnection system.

This type of differentials are electromagnetic operating, which allows not to lose the safety function in case of variations in supply voltage or loss of the neutral conductor; differential firing only occurs with the derivation in the active phase.
