Eaton ER4P-16N3PB Enclosed Rotary Disconnect - NEMA 4P
Part Number: ER4P-16N3PB
Quick Summary
The Eaton ER4P-16N3PB is an enclosed rotary disconnect switch designed for rapid isolation of electrical circuits in industrial control panels. Engineers often struggle with safe de-energization during maintenance, especially in dense switchgear where access is limited. This unit carries CE marking and a rugged NEMA 4P enclosure, delivering reliable protection against dust, water, and incidental abuse in harsh environments. With a 600 V rating and 16 A capacity, it supports compact motor-control and service-disconnect needs while staying compliant. By combining non-fused operation with a pistol-style handle, it delivers safer, faster interventions and reduces downtime and training costs for panels and enclosures.

FAQs
Ensure the enclosure cutouts and mounting orientation accommodate the 12 in depth, 7.5 in width, and 12.25 in height. The unit weighs 11.24 lb, uses a non-fused design with a pistol handle, and is designed for standard control panel installations.
Yes. The device features a NEMA 4P enclosure and CE marking, providing protection against dust and water ingress in harsher industrial environments.
It is rated for 600 V and 16 A, non-fused, with a NEMA 4P enclosure, designed for reliable service disconnects in industrial panels.
Ideal for service disconnects and motor-control panel applications in manufacturing and processing facilities, where safe de-energization and rugged protection are priorities.
The datasheet lists a warranty as Not Applicable. For maintenance, rely on the non-fused design to reduce fuse replacement tasks and follow standard inspection intervals for enclosure integrity and handle operation.
