The enclosed rotary disconnect features a non-fused selector, delivering fast and straightforward circuit isolation while eliminating fuse handling. This directly reduces arc-flash exposure for maintenance personnel and supports compliant lockout/tagout workflows, improving safety and uptime in manufacturing lines. With a 600 V rating and 80 A capacity, it accommodates mid-range industrial loads without overdesign, enabling compact panels with reliable performance. The NEMA 4X enclosure protects against dust, water, and corrosion, making it suitable for washdown and damp environments—minimizing service interventions and extending component life. Compatibility with FLC series flange cables simplifies field wiring and panel integration, reducing installation time and potential wiring errors. The non-fused design also lowers spare parts costs and simplifies routine maintenance in ongoing operations.

FAQs
When deploying the ER4X-80N6SB, ensure correct panel mounting and secure orientation for easy actuator access. Use with FLC series flange cables for clean wiring and verify the 600 V rating aligns with your control circuit. Confirm enclosure is closed during operation to maintain NEMA 4X protection and prevent environmental ingress.
The ER4X-80N6SB provides an 80 A amperage rating and a 600 V voltage rating, with a NEMA 4X enclosure. It is a non-fused, selector-type rotary disconnect, designed to isolate circuits safely and quickly while protecting control equipment from environmental exposure and incidental contact.
Yes. The device features a NEMA 4X enclosure, which offers protection against water, dust, and corrosion in harsh or washdown environments. This makes it well-suited for manufacturing floors, outdoor installations, and facility areas where moisture and contaminants are present.
The non-fused selector design enables rapid, safe isolation of circuits, reducing arc-flash risk during maintenance and enabling fast lockout/tagout procedures. Its robust enclosure protects from the elements, decreasing unexpected outages and prolonging component life, which translates to lower maintenance costs and shorter downtime for critical equipment.
