FAQs
Begin by verifying the 400A, 3P, 600V ratings align with your panel schedule, then prepare the panel wiring for a three-pole disconnect. Use the quick-connect terminals to reduce field wiring complexity, secure the bus connections, and torque fasteners to spec. The unit’s solid neutral fuse configuration supports safe start-up and clear fault isolation.
A 400A, 600V rating supports high-current motor loads and distribution without multiple devices, reducing overall switchgear footprint and potential points of failure. This enhances reliability, lowers installation costs, and simplifies coordination with upstream protection devices for motor control centers and line-side disconnects.
Yes. The unit features a NEMA 3R enclosure designed for moisture, dust, and weather resistance, enabling dependable operation in outdoor environments as well as semi-exposed indoor locations. This minimizes the need for additional weatherproof housings and supports seasonal maintenance planning.
The DH365NRKLP is UL Listed and designed with a rugged NEMA 3R enclosure, providing established safety and environmental protection. These certifications support compliance with many industrial codes and facilitate safe integration into automated lines and distribution systems.
Posi-Lok provides secure, positive handle locking for the safety switch, reducing chances of accidental disengagement during maintenance or vibration. This improves operator safety, minimizes unscheduled downtime, and lowers repair and replacement costs over the equipment’s life, contributing to a favorable total cost of ownership.
