Eaton Specification Sheet - DH464SNRKLP
Feature to business impact to application: The DH464SNRKLP uses a heavy-duty, four-pole configuration rated for 200A at 600V with fusible protection and a switched neutral, enabling clean, safe isolation of large motor loads and feeders. This translates to reduced arc-flash exposure during maintenance and fewer unplanned outages in production lines because the switch provides reliable mechanical interlock and secure disconnection. Application-wise, it fits industrial power distribution panels, motor control centers, and outdoor equipment housings where a robust disconnect is required. The Series K quick-connect design accelerates installation, reduces field wiring errors, and improves once-and-done commissioning for panel builders. Posi-Lok ensures a positive, removable connection that remains secure through vibration and thermal cycling, supporting long service intervals and lower maintenance costs. UL Listed certification further anchors compliance with safety standards, while the NEMA 3R enclosure protects against rain, dust, and corrosion in exposed environments. The unit’s dimensions and weight (18.57 in L, 40.89 in H, 13.68 in W, 140 lb) are indicative of its rugged construction, suitable for permanent installation with proper mounting hardware. Warranty terms of one year from installation or 18 months from shipment reinforce value and supplier support for industrial users.
