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.

Intriguing
Format: Kindle
An intriguing story that played out slowly while introducing some unique characters. The story became quite fascinating to read as these same characters provided startling revelations to their lives. As their relationships evolve, more drama and mystery is revealed adding to my fascination. I can’t wait to read more.

Outstanding Story!!!!!!!
Format: Kindle
Oh I loved this story. Sera is such an amazing, fun character. She has so much fire inside of herself. She has humor that makes you laugh with her sassy comments. The guys are fantastic. I don’t feel as if we really have gotten to know who and what they are but they are such a mix of fae. The story is extremely well written and developed. It had me pulled in and didn’t let go. There was so much action, drama, and suspense. Then we get to the ending and goodness there is so much going on. This ending was a major cliffhanger and I absolutely can’t wait to see what happens next.

Exceptional
Format: Kindle
I think this an exciting entertaining story different from other fantasy reverse harmen story. I love the 1st book in this series and hope it continues to weave a story of friendship, love and disappointment as well as sadness. The cliffhanger was gripping and held you in suspense that waiting until the next book was released was almost too much. I’m so glad I waited to read this series until the majority of the books were released. Katie May and Quinn Arthur’s are wonderful writers and I’m looking forward to reading more from both of them.

I don’t mind a cliffhanger,
Format: Kindle
but I dropped at least one star because of the obnoxious gloating of the author after the cliffhanger. Seriously - I don’t understand making your readers angry because you’re smug and expecting them to keep reading your books. I was very definitely enjoying the series. Now I have a bad taste in my mouth and mixed feelings about continuing the series.

The series as a whole so far 5/25
Format: Kindle
I read reviews before going into this book and I don't agree with one of the more harsh ones on the main trigger she had. It is stated clearly in the forward and it wasn't as blase as it was made out to be. It definitely is touched on more and hasn't just been brushed off as the series goes I definitely would recommend reading it. It's a good series just be for-warned I like the series as a whole. The characters are awesome I adore the fmc shes cute and adorable but also a badass. Though there are a bunch of holes for her that I feel like just got left out. The guys are interesting and shout out to yall for not making Gage a dragon. I'm tired of the broody ones who don't wanna talk aboit what they are being Dragons. Ki is my favorite You can definitely tell if is written by 2 different people though because the phrasing just doesn't match up and wouldn't be something people that age says. And it flip flops between them. I feel like there's substance without substance. We are 4 books in and we don't really know much back story on literally anyone more than right under surface deep. There are definitely favorite MMCs which is kind of disappointing since some get shoved to the wayside. Specifically both of the best friends. They're basically useless and it's made obvious as the books go on. As well as all the men are ungodly self deprecating. I enjoy the plot line for the most part like I said I enjoy the series its different and refreshing. I do feel like the series is being dragged out though unfortunately. And the latest cliff hanger was just meh. So hopefully the next book is the last one.
