Generator Cooling Fan Circuit Breaker

September 29, 2020, 09:46:55 am

The circuit breaker for my 12KW generator cooling fan mechanically failed.  Power Tech wants $76 plus shipping for Carling Technologies MM2-B-34-615-1-2BB-B-C.  I thought this would be a standard 15amp toggle switch CB, but it can take 23-25 amps for up to 34 seconds.  I'm sure I can use any type of switch, but I think I need the dynamic characteristics.  Can anyone locate an alternative?
