Eaton ER4P-100N3PR Enclosed Rotary Disconnect - NEMA 4P

Non-fused operation with a pistol handle minimizes contact points and simplifies field operations. This reduces maintenance time and enhances technician safety during isolation, commissioning, and testing. In modern control panels, that quick, safe disengagement helps minimize arc-flash risk and supports faster changeovers. With a 600 V rating and a 100 A current rating housed in a NEMA 4P enclosure, this switch delivers dependable performance in challenging environments. The rugged enclosure protects against dust, water, and incidental contact, lowering the likelihood of nuisance outages and costly repairs. It’s well suited for outdoor installations and damp indoor areas in automation lines and process machinery. Enclosed rotary disconnect design integrates seamlessly with Eaton Bussmann series offerings, simplifying procurement and spare parts strategy. The compact footprint, measured at 12 in depth, 12.25 in height, and 7.5 in width, fits common control cabinets without extensive layout changes. This helps contractors and maintenance teams plan installations with predictable space and faster commissioning. Compatibility with standard installation practices and pistol-handle operation reduces training time and accelerates safe energization. The non-fused configuration minimizes parts and maintenance complexity, supporting lean maintenance programs and lower total cost of ownership in facilities with frequent circuit isolation needs. Industry-standard compliance with CE marking and explicit NEMA 4P protection aligns with regulatory requirements across global sites. By delivering reliable isolation, durable construction, and straightforward installation, this Eaton switch can shorten downtime and improve overall equipment reliability in electrical protection and circuit control applications.
