Eaton Specification Sheet - DH466SNRKLP
The 600 A rating, four-pole configuration, and 600 V capacity enable dependable interruption of heavy machinery feeders, delivering safe isolation during maintenance and fault conditions. In practical terms for OEMs and maintenance teams, this translates to fewer switching faults, improved protective coordination, and reduced risk of arc-flash incidents in high-load lines. The Posi-Lok mechanical latch enhances reliability by resisting inadvertent disengagement in high-vibration environments, boosting uptime on conveyors, presses, and assembly lines. The fusible with switched neutral design simplifies fuse protection while enabling selective coordination and safer startup sequences, lowering total cost of ownership through simpler fault isolation and faster maintenance cycles. Its NEMA 3R enclosure plus UL Listing ensures weather resistance and regulatory compliance, enabling confident outdoor installations and compliance-driven deployments. Compatibility with Series K switchgear, standard mounting footprints, and a substantial footprint for service access support straightforward installation, electrical wiring, and long-term reliability in demanding facilities.
