Rated 5 out of 5 by from MCB for Air Compressors Inital high current peak on air compressors causes the standard 16A MCB to trip out. This is where this 20A is perfect. My load tests show trip point to be accurate. (on the unit tested)

Do you have to replace the unit after its tripped so many times, and if so how many?

Asked by: Nick1994
Hi, thank you for your product enquiry. BG MCBs do not have a designed or advised maximum number of trips before needing to be replaced, but if you are experiencing repeated trips over a relatively short period of time then this may indicate a potential fault with the device so at this stage it may be prudent to replace it.
