Description
Reliable 40A Circuit Protection for EV, Domestic & Commercial Use
ADR440C-030 – 4 Pole Type A 40A 30mA C Curve High Immunity RCBO
The WCED ADR440C-030 RCBO combines residual current, overload, and short-circuit protection in one compact device. As a result, it keeps your installation safe while reducing the need for multiple protective components.
This 40A 4-pole device uses Type A technology, which detects AC faults as well as pulsating DC currents. Therefore, it is ideal for electric vehicle charging points and also suitable for residential and commercial applications.
In addition, it comes with a switched neutral built in as standard. This design ensures that both live and neutral conductors disconnect during a fault, giving complete isolation and higher safety.
The ADR range also avoids unnecessary disruption. With this in mind, it only switches off faulty circuits and keeps healthy ones in service. Moreover, live and neutral do not need to be disconnected for insulation resistance testing, which saves time on site.
