FAQs
The ER53016UG is a three-pole enclosed rotary disconnect designed for indoor use in NEMA 1 environments. Mount it in standard panel cutouts, wire the three phases to the switch terminals, and connect the operator and lockout provisions per the Eaton installation guide. Ensure the panel is rated for 600 V and that wiring sizes support up to 16 A and the HP range up to 10 hp at the applicable voltage. The enclosure's dimensions (10.4 in L, 7.2 in W, 6.7 in H) facilitate retrofit into common footprints while preserving proper clearance and service access.
ER53016UG provides a 16 A amperage rating with a 600 V voltage rating and HP ratings of 3, 5, 10, and 10 hp at 208/240/480/600 V. It is a three-pole device within an enclosed rotary non-fusible design, making it suitable for isolating motors in standard DOL or VFD-driven applications. This combination supports common industrial motors and aligns with typical motor control center configurations, enabling a compact, reliable disconnect without oversizing hardware.
Yes, for indoor environments where dust and basic moisture are possible, the ER53016UG’s NEMA 1 enclosure and painted steel construction provide robust protection. While not rated for outdoor use or high IP environments, it delivers reliable isolation in typical workshop, factory floor, or control room settings. Its rigid three-pole arrangement, HP range, and UL CSA certifications further support its integration into standard panel builds and routine maintenance workflows without specialized mounting adaptations.
The ER53016UG is UL Listed and CSA Certified, aligning with recognized electrical safety standards for control gear and motor disconnects. These certifications reduce compliance risk during audits and facilitate procurement by meeting common code requirements for panel assemblies in North American facilities. When specifying for a project, reference the UL Listed and CSA Certified status to ensure compatibility with your safety programs and vendor qualification criteria.
The product carries Eaton’s warranty policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first.
