How hot can a SKAL3200 breaker run and be within limits? <br />Do you have any formulas or tables that can be used to calculate what temperature a breaker will reach with a known current running through it?<br />

Circuit breaker terminals on IEC 947-2 rated circuit breakers are permitted a 70 deg. C temperature rise above ambient. It a 30 deg. C ambient, for example, the terminals could be as high as 100 deg. C and be within limits. If the ambient is 30 deg. C, and the terminals are 47 deg. C, the rise is only 17 degrees, and is well within limits.
There are no tables or formulas to consult for temperature rise at different currents. All we have are the maximums given by the standards.
