Protection differential switch 40A 30mA (0.03A), category "B", 4 poles, to protect people from insulation/derivation problems in installations or electrical elements. Allows detection of sine and pulsed 50Hz signals with mixed components up to 1kHz and DC component signals


Use class "B" is suitable for protection and monitoring of computer equipment (UPS), frequency converters, three-phase battery chargers, electric vehicle chargers and photovoltaic installations. Class "B" RCDs can be considered suitable for all difficult applications, not only in terms of protection, but also of operational continuity.


In this type of RCD, tripping is ensured as in class A RCDs and also in the case of residual currents coming from rectified circuits in DC or high frequencies in AC. They provide protection in case of continuous power failures in three-phase networks, generated by controllers and frequency inverters, batteries, inverters, UPS/UPS power supplies.
