FAQs
Begin by confirming space and mounting holes align with the two-pole compact enclosure. Lockout/tagout the pistol handle, disconnect power, and remove the cover to access terminal blocks if required. Reinstall, restore power, and test with a multimeter. Follow NEC wiring practices and Eaton installation guidelines for a safe, compliant retrofit.
The unit is rated for 600 V and 100 A with a two-pole configuration and an enclosed NEMA 4 rating. It uses fuse type CF and a pistol-style handle to enable safe operation and quick service. Ensure your panel can accommodate these values and follow proper installation sequencing.
Yes. The NEMA 4 enclosure provides protection against dust, water, and weathering in many wash-down and outdoor areas when installed in a suitable enclosure. Verify mounting orientation and use appropriate sealing in your specific environment to maintain protection ratings.
This disconnect is CE marked, signaling compliance with EU safety and environmental requirements, and features a NEMA 4-rated enclosure for protective reliability. These certifications aid in regulatory audits, cross-border procurement, and consistent maintenance practices across facilities.
Maintenance benefits include reduced downtime due to predictable switching and easier lockout/tagout with the pistol handle. The enclosed CF fuse design minimizes exposure and wear. Over the asset life, these factors translate into safer operations, simpler spare parts management, and faster panel upgrades, delivering measurable lifecycle cost savings.
