Eaton Specification Sheet - DH363URKLC
Three-pole design ensures balanced switching for three-phase motors, improving isolation and reducing arcing during operation. This enhances switch life and lowers maintenance costs in high-cycle applications like conveyors and pumps. A 100A rating supports common industrial loads while keeping wiring simple and safe, reducing inrush and safeguarding personnel during disconnection. Cam-Lok fast-connect terminals enable clean, tool-free wiring and secure connections, dramatically reducing installation time and field wiring errors for panel builders and retrofit projects. The NEMA 3R enclosure delivers outdoor-rated protection, expanding deployment options to rooftops and exterior substations without additional housing. Series K construction with UL Listed certification supports standardized procurement, simplifying audits and ensuring regulatory alignment across facilities.
