FAQs
ER4-60N3PR is an enclosed rotary disconnect switch used to safely isolate electrical circuits in industrial power distribution. It is non-fused, rated for 60A and 600V, with a pistol handle for controlled operation. Ideal for panel feeders, motor-control circuits, and service disconnects in manufacturing and process environments where reliability and safety are paramount.
Yes. The ER4-60N3PR carries CE marking and features a NEMA 4 enclosure, which provides protection against dust, water, and other harsh conditions. This makes it suitable for outdoor installations, damp plant rooms, and areas subject to wash-downs, helping ensure regulatory compliance and safer operation across environments.
Install by selecting a suitable panel opening, securing the enclosure, and connecting the wiring per standard control-panel practices. Use the pistol handle to safely engage or disengage the switch, and observe proper lockout/tagout procedures during maintenance. Ensure voltage and current ratings meet the connected circuit requirements to prevent nuisance tripping or overheating.
ER4-60N3PR provides non-fused isolation with a robust 600 V, 60 A rating inside a protective NEMA 4 enclosure. It minimizes arc flash exposure during switching, simplifies maintenance without fuse management, and supports reliable panel isolation in demanding industrial applications, improving safety and uptime.
Applications include motor control circuits, feeders, and service disconnects in manufacturing lines, packaging, and process industries. It is especially valuable in environments requiring CE compliance and weather protection, where compact form factor and integration with Bussmann series components streamline installation and procurement.
