It fits a standard DIN rail, although the clip wasn't as easy as other MCB/RCBO devices to secure to the rail. Seems to work fine. Value for Money.

Good product

Alas my ring main do tripeth my RCD. What danger lurks. My two spurs shall vanquish the gremlin. But doth not a circuit breaker make safe a circuit? Only if it be de-rated.

Looks a quality product

After getting permission to get downtime at a dental surgery, to isolate the consumer unit to put a 6amp MCB, the part was faulty and the spring get tripping, had to leave the job to rush out and get another 1, leaving the dentists with no power.

Great value and adaptable
