The ER4X-200CF3PB uses an enclosed NEMA 4X-rated enclosure to protect internal components from washdown, dust, and corrosion, delivering higher reliability and reduced maintenance costs in harsh environments. Business impact: fewer unscheduled outages and longer service intervals, enabling more up-time in food & beverage, water treatment, and chemical processing facilities. Application: ideal for outdoor or wet locations where safety isolation is critical and enclosure integrity is non-negotiable. The 600 V, 200 A rating provides robust power isolation for motor control centers and machine panels, supporting scalable upgrades without changing disconnects. Business impact: improved protection coordination and fewer component substitutions; Application: new installs and retrofits in heavy industry. The pistol-handle operator enhances ergonomic safety, reducing operator slip risk during maintenance. Business impact: faster, safer lockout/tagout procedures; Application: routine servicing and emergency isolation. Fuse type CF integration enables coordinated protection and quick field replacement, reducing repair time and downtime. Business impact: lower maintenance costs; Application: circuits with CF fusing requirements. The unit’s 21 in depth, 15.74 in width, and 14.04 in height (and 14 lb weight) simplify cabinet planning, mounting, and service accessibility. Business impact: smoother retrofits and accurate space planning in existing control enclosures; Application: cabinet design and retrofit projects.

FAQs
The ER4X-200CF3PB is a three-pole, enclosed rotary disconnect designed for standard Eaton Bussmann enclosures. It measures about 21 in deep, 15.74 in wide, and 14.04 in high, with a pistol-handle operator for safe manual operation. Mounting aligns with typical panel cutouts; use the 600 V, 200 A rating to coordinate with upstream feeders and CF fuse protection for coordinated shutdowns.
This disconnect supports 600 V operation and 200 A current, with a NEMA 4X enclosure for rugged environments. It is CE-marked to satisfy European safety standards and uses CF fuse protection for rapid fault isolation. Plan for downstream protection coordination and compatible fusing to ensure fast clear fault conditions without unnecessary downtime.
Yes. The NEMA 4X-rated enclosure provides a weatherproof and corrosion-resistant shell suitable for washdown areas and harsh industrial settings. CE marking further confirms compliance with international safety requirements. This makes it a reliable choice for chemical plants, food and beverage facilities, and water treatment environments where exposure to moisture and contaminants is common.
Key benefits include a pistol-handle operator that improves ergonomic safety during maintenance and a CF fuse type that enables quick replacement and safer fault isolation. The enclosed design reduces exposure to energized parts, supporting safer lockout/tagout procedures and minimizing downtime from panel contamination or weather exposure.
Anticipated ROI comes from reduced unplanned downtime, fewer component failures due to a rugged NEMA 4X enclosure, and easier field service with CF fuse protection. The device’s durable construction and standardized Eaton Bussmann compatibility streamline parts sourcing, uptake in retrofits, and longer service intervals, delivering lower maintenance costs and faster, safer line changes.
