This RCBO is ONLY compatible with Live SRN Consumer Units (LSMCSRN**/100) With Live Electrical Dual Busbars. It is not suitable for standard consumer units or those requiring flying neutral connections.

The Live RNC140B-030N is a compact, high performance plug on neutral RCBO designed for fast installation and reliable circuit protection in modern consumer units. Featuring a double pole, bidirectional design, it delivers combined protection against overload, short circuit and earth leakage for maximum safety.

Key Features
Plug-on neutral design – no flying lead for faster install
40A B Curve – ideal for lighting circuits
Double pole switching – isolates both live and neutral
30mA sensitivity – enhanced protection against electric shock
Type A – detects AC and pulsating DC fault currents
Bidirectional – ideal for solar PV systems
Compact module – maximises space within the consumer unit
