Description
40A Curve B 30mA A Type RCBO – Compact RCBO, Switched Line & Neutral, 6kA
Heavy-Duty Protection for Power Circuits – Niglon RCBO1-40/30SSAX 40A RCBO
Niglon RCBO1-40/30SSAX
The Niglon RCBO1-40/30SSAX 40A RCBO is a compact and efficient circuit protection device, tailored for higher-load installations such as electric showers, cookers, and commercial socket circuits. With a Curve B tripping characteristic, it offers fast response to faults while avoiding nuisance tripping under normal load surges.
This RCBO features 30mA Type A residual current detection, protecting against both AC and pulsating DC leakage. Furthermore, the switched line and neutral design ensures safe and complete disconnection during fault conditions, enhancing compliance and safety across a range of applications.
Its slim 18mm width makes it a perfect fit for space-restricted consumer units, especially in upgrades and 18th Edition-compliant installations.
