Short circuit current rating
Suitable for use on a circuit capable of delivering not more than 200,000 rms symme-
trical amperes when protected by 600 V non-semiconductor fuses or 500 V minimum
inverse time circuit breakers.
•
Suitable for motor group installation on a circuit capable of delivering not more than
5,000 rms symmetrical amperes when protected by maximum 40 A, 600 V non-semi-
conductor fuses or 500 V minimum 40 A maximum inverse time circuit breaker.

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.
The table below list the permitted maximum branch circuit protection:

output current. To determine the output current rating at temperatures above 40 °C,
the output current should be derated by 3.0% per K between 40 °C and 55 °C.
An additional speed-dependent derating may be required. For details, refer to chapter
"Technical data and dimension sheets".
