Excellent Circuit Breaker Supplemental Protection

As an industrial electrician, I can attest to the reliability and efficiency of this circuit breaker. It provides excellent supplemental protection, withstanding high-industrial usage. Even when overloading occurred, I observed minimal damage to the connected equipment. The circuit breaker is easy-to-install and fits right into my existing electrical system. As my tests showed, it meets all the necessary safety standards for industrial and scientific applications. The only downside is that it…

Pros
  • Reliable and efficient, minimal damage, easy-to-install, meets all safety standards.
Cons
  • A bit pricey for some industrial businesses.

Slim but needs to be secured to stay in place

I like the thinness of the unit but it doesn't snap onto the 35mm DIN rail, for which it was developed. It seems to stay locked, but I can shake the rail and it will fall. I haven't disabled the switch yet, so I suspect it's still working as intended.

Pros
  • DIN rail mount for easy installation
Cons
  • Available in white only

Fragile. I wouldn't trust that.

Two important points. one. The Ue marking on it is given as AC400V 50Hz. I live in North America where 60Hz is used. I'm not sure if it's some sort of maximum rating, but searching the internet tells me it's bad and can cause the circuit to shut off faster. Two. The clamps holding the block to the rail broke at one of the breakers. Looks like poor design and the plastic clips are brittle. I think keep looking

Pros
  • High-density design 13 mm thick
Cons
  • Some small things
