FAQs
The DH363NRKLP is designed for straightforward integration in three-phase panels. Ensure compatibility with Series K devices, connect the fusible with solid neutral configuration per the Eaton documentation, and secure the enclosure to a clean, grounded chassis. Use the Posi-Lok feature during handle engagement to confirm a secure, locked position before energizing the circuit, and verify wiring conformity with local electrical codes to minimize commissioning time.
This switch is rated for 100 A, 3P operation at 600 V and comes in a NEMA 3R enclosure, UL Listed for safety and reliability. The fusible with solid neutral design supports proper fault isolation and protection coordination. Its rugged construction is intended for demanding environments, reducing risk of arcing and improving uptime in production lines and heavy machinery controls.
Yes. The unit uses a NEMA 3R enclosure, which provides protection against rain, sleet, and moderate outdoor exposure. UL Listing further confirms compliance with industry safety standards. This makes it a solid choice for outdoor switchgear, remote substations, and exposed machine rooms where reliability and weather resistance are critical.
The DH363NRKLP carries UL Listed certification and uses a NEMA 3R enclosure, designed for durable outdoor and industrial installations. While CE or SIL specifics aren’t listed in the provided data, UL Listing and NEMA 3R are strong indicators of compliance for many North American industrial environments and equipment safety programs.
Investing in the DH363NRKLP can reduce downtime through reliable fault isolation and faster fuse changes via Posi-Lok, lowering maintenance labor and outage duration. Its rugged enclosure and 600 V rating support long service life in harsh environments, decreasing replacement frequency and aiding compliance with safety standards, which collectively improve total cost of ownership over the system lifecycle.
