Differential SUPERINMUNIZED "YES" 2x40A 30mA with European certification and 2 year warranty. This Superimmunized Differential ("SI") is the solution for untimely tripping of the differential caused by lightning, fluorescent luminaires and "abrupt" power maneuvers in the electrical network. Other triggers are high frequencies and harmonic components.

The installation of this superimmunized differential is highly recommended by electricians in homes and offices where the differential says that it "jumps" very often without there really being an apparent cause, with a diagnosis that attributes the reason to the existence of components harmonics in the electrical network (although the reasons can be multiple and its study is expensive and complex). Normally it is solved or at least mitigated, with the installation of this superimmunized differential .

This superimmunized differential for DIN rail installation allows to guarantee the operation and correct operation with security in front of problems that are present in homes and offices, such as: networks disturbed by storms and lightning, engine start, strong powers coming from ovens or elevators close, high degree of harmonics, usually caused by power supplies of electronic equipment and computers, among others ...

Class A protection "SI" of our superimmunized differential, incorporates a high frequency filter , which prevents differential blocking and keeps it prepared to act against dangerous defects, even with a circuit that accumulates the energy of the transient (harmonics), which allows to produce the shot, if it is a real problem, or block the untimely shot.

Details of the superimmunized differential

We are facing one of the superimmunized differentials of the market with better value for money.

This superimmunized differential is indicated for untimely shots caused by lightning, fluorescent lighting and sudden maneuvers in the network, sometimes caused by the presence of large engines, elevators, etc.

Other factors especially indicated are when there are high frequencies and continuous components.

Nowadays, it is a product whose installation is highly recommended by professionals in installations where the differential "jumps" quite frequently without an apparent cause, which is often diagnosed as harmonic components (although the reality is that the motives they can be multiple and their study is expensive) and that is usually solved, or at least mitigated, with the installation of a superimmunized differential .

Although electricity is something very serious, the replacement is very simple by individuals, always taking the appropriate measures in terms of safety and precaution, disconnecting the power supply of the house before undertaking the rematch of your old differential by this superimmunized differential .
