Short Circuit Current Rating
Suitable for use on a circuit capable of delivering not more than 65,000 rms symmetri-
cal amperes 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 in-
verse time circuit breakers having an interrupting rating not less than 65 kA rms sym-
metrical amperes.
Suitable for motor group installation on a circuit capable of delivering not more than
65,000 rms symmetrical amperes when protected by 600 V maximum non-semicon-
ductor 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.
Branch Circuit Protection
Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes.
For maximum branch circuit protection see table below.
Motor Overload Protection
The devices are provided with load and speed-sensitive overload protection and ther-
mal memory retention upon shutdown or power loss.
The trip current is adjusted to 150% of the rated motor current.
Use 60/75 °C copper wire only.
Tighten terminals to 17.7 – 21.24 in-lbs (screw connect terminals only).
SCCR: 65 kA /500 V when protected by
Non-semiconductor fuses
(currents are maximum values)
40 A max./600 V
