20A Curve B 30mA Bi-Directional A Type RCBO – Compact RCBO, Switched Line & Neutral, 6kA
Smart Protection for Small Power and PV Circuits – Niglon RCBO1-20/30SAX2 20A RCBO
Niglon RCBO1-20/30SAX2
The Niglon RCBO1-20/30SAX2 20A RCBO delivers compact and dependable circuit protection for radial socket outlets, small heating loads, and PV-ready boards. Its bi-directional operation means it protects circuits from earth leakage and overcurrent faults, whether power flows in the normal or reverse direction.
This functionality is especially important in solar PV installations, where energy exported from an inverter may travel back through the protective device. Unlike standard RCBOs, this model continues to operate and trip correctly regardless of current flow—ensuring full compliance and peace of mind.
With 30mA Type A RCD sensitivity, Curve B tripping, and switched line and neutral, it supports safe, efficient, and space-conscious installations in any 18th Edition board.
