For retrofits, ensure space for a four-pole device, permit access for vertical mounting, and align with 18.57 in depth, 38.15 in height, and 13.68 in width. Use Cam-Lok connections to simplify wiring, and verify the NEMA 3R enclosure is appropriate for the installation environment. Follow standard electrical codes during mounting and termination.
The DH423SNRKLC is rated for 100A at 240V with four poles and fusible with switched neutral. This configuration provides robust isolation and selective fault control, reducing arc energy during disconnects. Ensure compatible feeders and motor loads are within 100A and that protective devices upstream are coordinated to prevent nuisance trips.
Yes. The device uses a NEMA 3R enclosure designed for outdoor or semi-exposed installations, providing weather-resistant protection. While UL Listed confirms safety compliance, verify site conditions and ensure that installation clearances and venting are appropriate for long-term operation in the intended environment.
The DH423SNRKLC carries UL Listed certification, confirming compliance with recognized safety standards. The NEMA 3R enclosure rating further supports outdoor and rugged indoor use. Additional manufacturer guidance covers installation practices and warranty terms under Eaton’s policy 25-000.
Maintenance primarily involves periodic inspection of connections and enclosure integrity; the Cam-Lok connections help reduce re-wiring time during service.
