Ground Fault Circuit Breaker, 32 Amp 120V AC DIN Rail Mount Residual Current Circuit Breaker, Thermal-Magnetic Trip, Earth-Leakage Protection 1PN RCBO C32

Working Reconmend

just what I needed to install a "WALK IN TUB"

This GFCI breaker is rated for 20 amps at 230v. It comes with a short piece of DIN RAIL and two mounting screws, which is a useful option for quick mounting this unit. It has a good throw, and feels solid and is not hard to install on the DIN RAIL like some of the rail mounted equipment is. It has the standard GFCI reset. Another useful feature is the mechanical indicator that shows red or green when the breaker is set or tripped. It has a small viewing window on the top left that shows on or off status. No issues so far with it.

This looked like a nice little circuit breaker. I mounted it to DIN rail and wired it into a circuit. After applying power I opted to test the GFCI function pressing the test button quickly. The breaker tripped off as it should, but hummed loudly for several seconds before going quiet. Seemed odd.I reset the breaker and tried again, this time just a normal quick trip. Reset again and pressed the button, holding it in for a second or two, the breaker hummed loudly again then a "pop" sound, then smoke came out of the breaker. I had fried the GFCI test circuit. Probably burned out a capacitor a resistor. I was surprised that simply pressing a test button could destroy the circuit breaker.I never got a chance to test the over-current protection... tossed it in the trash.Maybe I shouldn't have pressed the button more than instantaneously, so I give it two stars in case it was my fault, but I still don't like the design. No instructions included.
