Eaton Specification Sheet - ER53030UW
Stainless steel, NEMA 4X enclosure provides superior corrosion resistance and washdown suitability, reducing maintenance cycles and extending service life in outdoor or humid facilities. In practice, this translates to higher uptime in process plants and lower spare-part costs when you can rely on a single enclosure across multiple lineups. The device offers 30 A amperage with HP ratings up to 20 hp across 208–600 V, delivering reliable motor isolation without oversizing your switchgear, which reduces initial capital expenditure and panel footprint. Three-pole construction in the R-Series delivers consistent, three-phase isolation, simplifying wiring, start-up sequencing, and future scalability in tight control cabinets. UL Listed and CSA Certified, the assembly meets essential electrical standards, lowering risk during audits and easing procurement for regulated environments. Its compact footprint—11 in L × 7 in H × 8 in W, and a 6.2 lb weight—facilitates faster installation and easier field service across multiple lines. A one-year warranty, extendable by policy, further reduces total cost of ownership.

FAQs
ER53030UW is a three-pole, enclosure-based disconnect designed for standard control-panel installations. Its dimensions (11 in x 7 in x 8 in) and weight (6.2 lb) support straightforward mounting in common panel spaces. The stainless steel NEMA 4X enclosure provides a rugged, corrosion-resistant fit for indoor and outdoor installations, while wiring footprints align with typical terminal layouts to simplify field wiring and future maintenance.
This model delivers 30 A continuous amperage with HP ratings of 7.5, 7.5, 15, and 20 hp across voltages of 208, 240, 480, and 600 V. It is a three-pole, enclosed rotary non-fusible switch rated at 600 V. These specifications support safe motor isolation for small to mid-size three-phase machines, conveyors, pumps, and process equipment without oversizing the switchgear.
Industries such as manufacturing, water treatment, chemical processing, and food & beverage where washdown and corrosion resistance are critical benefit from the NEMA 4X stainless enclosure and UL/CSA certifications. Use cases include motor control centers, machinery isolation in conveyors and pumps, and process equipment that requires reliable, code-compliant disconnects in harsh environments.
The ER53030UW carries UL Listed and CSA Certified marks, validating compliance with recognized safety standards. The NEMA 4X enclosure reinforces protection against dust, water ingress, and corrosion. These certifications simplify regulatory approvals, supplier qualifications, and customer audits for facilities subject to electrical-safety codes and industry standards.
The unit includes a one-year warranty (18 months from shipment in some policies) and is built for long service life in demanding environments, reducing maintenance downtime. Its stainless steel enclosure and compact footprint lower field labor costs during installation and service, while UL/CSA certifications minimize compliance-related risks, contributing to lower total cost of ownership over the asset lifecycle.
