Observe the following notes for UL-compliant installation:
• Use 75 °C copper wire only.
• DRC.. uses cage clamp terminals
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.
• DRC.., the max. voltage is limited to 500 V.
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.
• DRC.., the max. voltage is limited to 500 V.
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.
• DRC.., the max. voltage is limited to 500 V.
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.
