FAQs
The ER4X-200CF3PR is a three-pole disconnect rated at 600 V and 100 A, designed for standard three-phase motor control panels. Its CF fuse configuration and NEMA 10 enclosure support common industrial switchgear layouts while complying with CE marking requirements, making it suitable for many regional installations.
Install the unit in a properly sized control cabinet with adequate clearance for service and cooling. Mount securely using standard hardware, connect the three-phase conductors to the switch, ensure the CF fuse is correctly seated, and apply the pistol-style handle for operation. Verify CE compliance and door interlocks as part of your lockout/tagout procedures.
The CF fuse type provides fast fault isolation and controlled current interruption, reducing arc flash exposure and protecting downstream equipment. Enclosure protection minimizes dust and splash ingress, extending service life in demanding industrial environments and simplifying compliance with safety standards.
Yes, the ER4X-200CF3PR is CE marked, indicating conformity with applicable European safety directives. The NEMA 10 rating means the enclosure is designed for indoor, dry locations with a non-ventilated enclosure, suitable for general purpose electrical protection in controlled environments.
The unit measures approximately 21 inches in length, 14.04 inches in height, and 15.74 inches in width, with an estimated weight of about 14 pounds. Use these dimensions to plan panel cutouts, clearance for maintenance, and mounting clearances in new or retrofit installations.
