40A Type A Mini Bi-Directional RCBO – 100mA B Curve
Designed for Specialist Applications Including Solar and PV Installations – Live Electrical AMR140B-100 100mA RCBO
Live Electrical AMR140B-100 – 100mA Bi-Directional Type A RCBO
The Live Electrical AMR140B-100 offers dependable protection for 40A circuits where standard 30mA RCDs may lead to nuisance tripping. With 100mA Type A sensitivity, it provides stability and effective disconnection during earth fault conditions, making it an excellent choice for selected solar and PV installations.
This RCBO combines overload, short circuit, and residual current protection in one compact unit. The B Curve tripping profile ensures rapid response under fault conditions, while the 6kA breaking capacity protects against high fault currents. The bi-directional design enhances installation flexibility, especially where energy sources like PV panels feed into the circuit.
Important: This device must not be used on circuits requiring 30mA RCD protection. Always assess the installation thoroughly and ensure compliance with BS 7671 before fitting.
