FAQs
Yes, the ER4-1200N3PB is designed for standard industrial panels and MCCs with compatible mounting arrangements. It supports 600 V systems at up to 1200 A and uses a pistol handle for safe operation. Refer to Eaton's catalog for mounting dimensions and enclosure compatibility to ensure proper fit and safe clearance.
Rated at 600 V and 1200 A, with a NEMA 4 enclosure to withstand dust and water exposure. Being non-fused means it provides safe isolation without internal fusing, relying on external protection in the circuit. This configuration minimizes downtime during maintenance while meeting industrial protection standards.
Ideal for motor control centers, large equipment feeders, outdoor substations, and service entrances in manufacturing and processing facilities. Its rugged enclosure and high-current rating support critical loads and reliable isolation. It's well-suited for retrofit projects where durable isolation devices are required.
The unit is CE marked, indicating compliance with European safety and performance requirements. It carries a NEMA 4 enclosure rating for harsh environments, enabling outdoor use. While UL/CSA listings are not specified here, CE and NEMA 4 support widely accepted industry standards for many global installations.
Non-fused protection minimizes internal consumables, reducing replacement parts and maintenance intervals. Pistol handle design and robust enclosure improve safety and operator efficiency during switch-out. Overall, investing in a high-current, rugged disconnect reduces downtime and supports asset uptime in critical electrical protection schemes.
