FAQs
The ER12-100CF3PB is designed to provide safe electrical isolation for three‑phase circuits within industrial control panels. It protects personnel during maintenance, enables immediate power disconnection, and supports reliable operation in harsh environments. Its three‑pole arrangement and rugged enclosure suit motor control centers, panel boards, and service disconnect applications.
Yes. The ER12-100CF3PB is rated for 600 V and a current rating of 100 A in a three‑pole configuration, making it suitable for typical industrial drives, machine tools, and panel-mounted disconnects in 600 V three-phase systems. Its NEMA 12 enclosure provides protection in dusty or damp environments.
The ER12-100CF3PB is CE marked, reflecting EU compliance for safety and performance. It features a NEMA 12 enclosure rating for dust and moisture protection and supports 600 V, 100 A operation with a three‑pole configuration. The fuse type CF adds integrated overcurrent protection as part of the disconnect assembly.
Operation is designed for quick, secure isolation using a pistol-style handle, enabling rapid fault isolation and safe power shutdown during maintenance. The enclosed design reduces arc exposure and dust ingress, while the CF fuse type provides reliable overcurrent protection. Always follow lockout/tagout procedures and verify absence of voltage before servicing.
The unit has a compact footprint with dimensions approximately 11.8 in (length) × 10.8 in (height) × 9.84 in (width) and a weight around 6 lb, facilitating easier panel integration. It is compatible with standard control panels and motor control centers requiring 600 V, 100 A, three‑pole disconnects and CE/NEMA 12 compliance for rugged environments.
