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.

They last for months
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
This is my second order of this product. I have 2 medium size dogs and they love them. The nice thing is a 3 pack of these is that they will last them for a few months.

My four approve
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
My dogs, which I have 4, 2 labradors, one Jack Russell and one medium smallish mixed breed dog, all really love the bones. Three of them seem to be vigorous chewers the mixed breed girl being the toughest one on bones. These bones are holding up really well and the dogs really seem to like them. The dogs have not been able to get any big chunks off of the bones so I feel safe letting them have them even when I’m not watching. I would recommend these to Pet owners.

I have a medium sized dog and these were to big for him. A bigger dog would love them. Great for chewers.
