Eaton ER1-200N3PB Enclosed Rotary Disconnect - NEMA 1
Part Number: ER1-200N3PB
Quick Summary
The Eaton ER1-200N3PB enclosed rotary disconnect switch provides safe isolation for 200 A, 600 V circuits. Many engineers struggle with compact, reliable isolation that won’t compromise maintenance or safety in dense switchgear. CE marking and a NEMA 1 enclosure rating support compliant indoor installation, while fuse-class J and a pistol-style handle boost safety and operability. In practice, this translates to faster commissioning, easier fault isolation, and scalable protection for panel boards and machine controls. For procurement teams, standardization across Eaton Bussmann series reduces spare parts diversity and accelerates vendor sourcing. Field technicians benefit from consistent handling, clear labeling, and widely available replacement components in service catalogs.

Eaton Specification Sheet - ER1-200N3PB
The enclosed design pairs fuse-class J protection with a pistol-style handle, improving operator safety and reducing arc-flash exposure during operation. This configuration minimizes handling errors and supports quick, one-handed switching in cramped panel spaces, making it ideal for compact switchgear and control cabinets. With a 200 A, 600 V rating, the ER1-200N3PB handles mid-size feeders with a comfortable safety margin, reducing the need for oversized disconnects and expediting maintenance windows. The NEMA 1 enclosure and CE marking offer indoor-use reliability and international compliance, simplifying procurement for multinational facilities and regulatory audits. Compatibility with Eaton Bussmann series protection devices streamlines installation, reduces spare parts complexity, and supports scalable protection across multiple lines of defense. Durable construction and widely available service parts enable longer field life and lower total cost of ownership. The pistol handle and clear labeling also shorten technician training time, improving site safety and productivity in routine switching.
