FAQs
ER4X-1200N3PB is rated for 600 V and 1200 A, designed as a non-fused enclosed rotary disconnect with a pistol handle. It integrates with typical switchgear and MCC configurations, offering straightforward isolation while maintaining compliance with CE standards and NEMA 4X protection for rugged environments.
Best suited for control panels, motor control centers, and switchgear in industrial facilities where reliable, non-fused power isolation is needed. Its 600 V / 1200 A rating and NEMA 4X enclosure support high-current, weather-resistant installations with safe maintenance access.
The ER4X-1200N3PB is CE marked, reflecting compliance with European safety standards, and features a NEMA 4X enclosure for rugged protection. These certifications support broader regulatory alignment and onsite safety expectations in modern facilities.
Leverage the NEMA 4X enclosure to protect against dust and moisture, and use the pistol-style handle for rapid, secure operation during lockout/tagout procedures. Plan for proper panel mounting, clear labeling, and adherence to CE-compliant safety practices to maintain long-term reliability.
A non-fused disconnect reduces fault-current exposure during maintenance, simplifies sourcing for replacements, and minimizes downtime associated with fuse maintenance or replacements. This translates to lower maintenance labor costs, quicker isolation during servicing, and improved overall uptime for critical power systems.
