When should I protect my installation with type-B residual current protection?

We want to let you know about the applicable laws and all the key aspects you need to take into account to select the right RCCB for your installation. The evolution of electronics in electrical installations means that we need to know what type of residual current protection is ideal for each type of load in order to properly protect both people and the installation itself.

To do this, we present the new type-B residual current protection family, which is the kind of protection you need when there may be an alternating, pulsating or direct current leak. Find out why you should use type-B residual current protection devices and what benefits they bring to your installation.

Avoid risks by selecting the right protection for each type of load

Type-A and AC residual current protection devices do not detect DC residual currents, and can trip spuriously or lock up, jeopardizing service continuity and putting the installation and/or personnel at serious risk.

The protection required by the manufacturers themselves to protect their loads

Manufacturers of devices with power electronics, including variable-speed drives, UPS, EV charging points, etc., require type-B residual current devices to be installed to ensure their loads are properly protected.
