FAQs
Begin by verifying the two-pole configuration and that the panel enclosure meets NEMA 4 protection. Mount the unit on a flat panel surface with adequate clearance, connect line and load conductors according to the wiring diagram, and secure the pistol handle for easy actuation. Ensure compatible fuse coordination with CF-type fuses and verify CE compliance during final commissioning. Properly size wiring, provide appropriate thread engagement for mounting hardware, and test operation with the control circuit de-energized.
The ER04-100CF2PR is rated for 100 A at 600 V, two-pole operation, and follows NEMA 4 enclosure standards. It uses fuse type CF for protection coordination and is CE marked for compliance. This combination supports robust service disconnect functionality in both indoor and outdoor industrial environments, with clear operability in standard control panels and machines.
Yes. The device carries a NEMA 4 rating, which provides protection against dust, water ingress, and mild weather exposure when installed properly. This makes it appropriate for outdoor control panels and machine enclosures in industrial settings, provided the installation complies with mounting guidelines and local electrical codes.
The ER04-100CF2PR is CE marked, indicating compliance with applicable European directives for safety and environmental aspects. Its NEMA 4 enclosure rating further supports compliance in regions adopting NEMA standards for outdoor and rugged environments. When selecting this device, ensure it meets your regional electrical standards and installation practices as part of the overall protection strategy.
Regular inspection of the CF fuse elements, pistons, and mounting hardware helps maintain protective coordination and actuation reliability. Since the unit integrates with Eaton Bussmann components, consolidating spares and standardizing the CF fuse family can lower stocking costs. The robust enclosure and CE compliance minimize downtime due to nonconformance and simplify replacement in aging control systems.
