Eaton DH325NRKLC Heavy Duty Safety Switch - Cam-Lok
Part Number: DH325NRKLC
Quick Summary
The Eaton DH325NRKLC heavy duty safety switch provides reliable isolation for three-phase power distribution in industrial facilities. When uptime matters, complicated wiring and hard-to-reach disconnects slow maintenance and raise safety risk for technicians. This unit carries UL Listed safety certification, a NEMA 3R enclosure rating for harsh indoor/outdoor environments, and a robust Cam-Lok connection for fast, vibration-resistant wiring. Series K design with fusible solid-neutral configuration supports safe fault isolation, while the 400A, 240V, three-pole construction suits demanding processes. In practice, this translates to safer isolation, faster service, and lower total cost of ownership for industrial electrical protection and heavy-duty disconnect switching.
