FAQs
ER12-200CF3PR-CST is designed for standard industrial control panels with a three-pole disconnect and a pistol-handle actuator. Its 21 in length, 14.04 in height, and 15.74 in width fit common enclosure footprints, simplifying retrofits and OEM deployments. The unit’s CF/CST fuse compatibility supports existing protection schemes, reducing redesign time and ensuring straightforward mounting and wiring in new builds.
This enclosure is rated for 600 V operation with a three-pole configuration. The Amperage Rating field lists 100 A, while the catalog number ER12-200CF3PR-CST denotes a 200 A class capability in typical Eaton Bussmann practices. Always verify the exact amperage rating on the datasheet for your specific installation to ensure proper fuse coordination and short-circuit protection.
The ER12-200CF3PR-CST is CE marked, signaling compliance with European electrical safety and performance standards. It carries a NEMA enclosure rating in its description and is designed for robust industrial environments. For projects with strict regional requirements, confirm any country-specific certifications beyond CE and ensure enclosure protection meets site norms.
CF and CST fuse types provide fast-acting and time-delay protection suitable for diverse motor and load profiles. Using CF/CST with this disconnect allows coordination with feeder breakers and reduces nuisance tripping while protecting downstream equipment. This compatibility helps maintain uptime and simplifies stocking of common Eaton Bussmann protection components.
The enclosed rotary disconnect switch improves safety and minimizes unplanned downtime by delivering reliable isolation during maintenance. Its CE marking and NEMA 12 enclosure support regulatory compliance and environmental resilience in dusty or damp environments. In addition, the compact footprint, pistol-handle operation, and CF/CST fuse compatibility reduce installation time and spare parts costs, delivering faster maintenance cycles and longer equipment life.
