Enclosed, three-pole rotary disconnect provides clear, lockable isolation for 600 V circuits. This design reduces arc-flash risk during maintenance and prevents accidental re-energization, delivering safer servicing windows and easier lockout/tagout procedures. It is ideal for industrial control panels and motor feeders where reliable isolation is essential to safe startup, preventive maintenance, and consistent process control. Fuse type CF/CST compatibility and a pistol-handle lever translate to fast, controlled disconnection. The business impact is shorter maintenance windows, lower labor costs, and reduced risk of unintended equipment restarts after service. In practice, technicians can sequence isolation events quickly while maintaining operator ergonomics and clear status indication in crowded control rooms. Robust CE-marked construction aligns with international safety standards, supporting multi-region deployments, and a NEMA 19 enclosure rating provides dependable protection against dust and incidental contact in typical factory environments. Combined with a 21 in length and generous depth, this unit integrates with standard industrial cabinets without requiring custom enclosures. Three-phase compatibility ensures it supports common motor-control and feeder applications, while the 100 A current rating provides a healthy margin for startup surges, preventing nuisance trips and avoiding oversizing across the panel. The modular design simplifies future upgrades as production lines expand. Compact dimensions—21 in length, 15.74 in width, and 14.04 in height—along with a 14 lb weight ease transportation and field installation. Lightweight yet sturdy construction improves on-site handling and reduces the risk of dropped components during retrofit projects. With CE compliance and standard CF/CST fuse compatibility, maintenance crews can source spare parts and accessories from mainstream suppliers, cutting lead times and supporting safer lockout/tagout sequences in modern facilities.

FAQs
Follow standard panel procedures: verify enclosure space, mount the 21 in x 15.74 in x 14.04 in unit in a suitable cabinet, and secure with proper mounting hardware. Wire the three input/output terminals for a three-pole configuration, connect the CF/CST fuse block as required, and ensure the pistol-handle actuator is accessible for safe disconnection. Confirm CE compliance and perform a voltage check before energizing.
Key ratings are 600 V maximum voltage, 100 A current, and three-pole operation, with a NEMA 19 enclosure. This combination supports standard industrial feeders and motors, ensures safe isolation, and provides margins for startup surges. It is compatible with CF/CST fuse types for flexible protection and maintenance workflows.
Yes. The ER04-200CF3PR-CST is designed for 3-phase circuits and motor feeders in industrial settings. It provides reliable isolation during startup, maintenance, and fault recovery. Ensure your motor current stays within the 100 A rating and install CF/CST fuses to match protection requirements for safe and compliant operation.
It is CE marked, indicating compliance with European safety standards. The enclosure is rated NEMA 19, offering rugged protection in typical factory environments. While specific UL listings are not shown here, CE compliance and standard NEMA protection support broad regulatory alignment for many facilities.
