Product Overview

The LIVE Electrical RKB140B-030 Type B RCBO is a high-capacity, single-module residual current breaker with overcurrent protection, engineered to deliver advanced circuit safety in demanding electrical installations. It provides effective protection against overloads, short circuits and earth leakage faults, while supporting applications where DC residual currents may be present.

This Type B RCBO is specifically designed to detect AC, pulsating DC and smooth DC residual currents, ensuring compliance with modern electrical safety requirements. Its bi-directional capability makes it ideally suited to renewable energy systems and power electronics where current flow can occur in either direction.

With a rated current of 40A, a 30mA residual current sensitivity and a 6kA breaking capacity, the RKB140B-030 is an excellent choice for protecting high-load circuits such as EV charging installations, solar PV inverters, heat pumps and other advanced electrical equipment.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.
