I use these products all the time in my work. Let me say that the purpose of a circuit breaker or fuse is to prevent a fire (and in some special cases, equipment damage). This means that the size of the fuse or circuit breaker must match the size of the cable connected to it (in special cases the size must be lower than the maximum current that the device to be protected can handle). SAE wire sizes typically increase by 5 amps, with 32 amps falling somewhere around the National Electric Code 10 (Copper 60c) limit - that's 30 amps in the code. The tabs on this switch easily handle MUCH larger conductors and grip 14 gauge stranded wire well. significant current. DIN rail mounting makes it a good candidate for mounting in an industrial cabinet, but in general I would use a lower trip rating to protect smaller wires and look for smaller terminals. The price is very cheap!
