Short circuit current rating
DRC1/2
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.
•
DRC3/4
Suitable for use on a circuit capable of delivering not more than 5,000 rms symmetri-
cal amperes when protected by 600 V non-semiconductor fuses or 500 V minimum in-
verse time circuit breakers.
•
DRC1/2/3/4
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 with an
interrupting rating of 5 kA minimum.

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:
Series
DRC..
Motor overload protection
DRC.. is provided with load and speed-sensitive overload protection and thermal me-
mory retention upon shutdown or power loss.
The trip current is adjusted to 150% of the rated motor current.
Ambient temperature
DRC.. is suitable for an ambient temperature of 40 °C, max. 60 °C with derated output
current. To determine the output current rating at temperatures above 40 °C, the out-
put current should be derated by 3.0% per K between 40 °C and 60 °C.
An additional speed-dependent derating may be required. For details, refer to chapter
"Technical data and dimension sheets".
Wiring diagrams
For wiring diagrams, refer to chapter "Electrical installation".
DRC.., the max. voltage is limited to 500 V.
