FAQs
The DH465UGKSNLPR is designed for indoor use in a NEMA 1 enclosure, suitable for control panels and machine rooms. Plan for a robust mounting surface, ensure proper alignment with the Posi-Lok reverse pin for correct handle orientation, and verify upstream protection coordination in your electrical distribution to maximize safety and minimize downtime.
This switch is rated for 400A and 600V with four poles, unfused. It handles high-current motor loads and provides reliable isolation without internal fusing, allowing you to pair it with upstream breakers. In practice, this supports clear fault clearing and improved protection coordination in demanding drive and conveyor applications.
The Series K design and NEMA 1 enclosure support retrofits where indoor, high-reliability isolation is needed. Its substantial footprint (approximately 32.87 in depth, 74.34 in height, 16.1 in width) should be planned into panel layouts and service clearances. Compatibility with existing upstream protection simplifies integration in established control architectures.
The DH465UGKSNLPR carries UL Listed certification, aligning with common industrial safety and electrical standards. This supports procurement approvals and regulatory compliance in many regions, reducing qualification risk during audits and construction. While it does not list CE or IP in the provided data, its indoor NEMA 1 enclosure is suitable for protected indoor environments.
Unfused configurations typically reduce parts exposure and maintenance complexity, since there are fewer internal fuse assemblies to monitor. The DH465UGKSNLPR’s rugged build and Posi-Lok mechanism contribute to longer service intervals and lower lifecycle costs, while UL Listed certification provides assurance for ongoing compliance and reduced risk of unplanned downtime.
