Short Circuit Current Rating

Suitable for use on a circuit capable of delivering not more than 65,000 rms symmetrical amperes (models with maintenance switch not more than 5,000 rms) when protected by when protected by 600 V maximum non-semiconductor fuses (Class CA, CB, CD, CF, G, J, K-1, K-5, RK1, RK5, T) or when protected by 500 V maximum inverse time circuit breakers having an interrupting rating not less than 65 kA rms symmetrical amperes..

Suitable for motor group installation on a circuit capable of delivering not more than 65,000 rms symmetrical amperes (models with maintenance switch not more than 5,000 rms) when protected by 600 V maximum non-semiconductor fuses (Class CA, CB, CD, CF, G, J, K-1 , K-5, RK1, RK5, T) or when protected by 500 V maximum inverse time circuit breakers having an interrupting rating not less than 65 kA rms symmetrical amperes.

The max. voltage is limited to 500 V.
