Description
40A Curve B 30mA Bi-Directional A Type RCBO – Compact RCBO, Switched Line & Neutral, 6kA
Heavy-Duty Circuit Protection for Solar and Power Loads – Niglon RCBO1-40/30SAX2 40A RCBO
Niglon RCBO1-40/30SAX2
The Niglon RCBO1-40/30SAX2 40A RCBO offers robust, compact protection for high-load circuits such as electric showers, cookers, and heating systems. It features a Curve B tripping profile, 30mA Type A RCD, and bi-directional current detection—making it ideal for solar-ready installations.
In PV systems, exported energy may cause reverse current flow through protective devices. Many RCBOs are not designed for this. However, this model continues to monitor and disconnect safely regardless of direction, offering true PV compliance.
Its compact 18mm footprint fits neatly into modern boards. With switched line and neutral disconnection, it allows safe testing and maintenance—ensuring both safety and convenience.
