Eaton Specification Sheet - ER4P-100CF2SR
Feature: The enclosed rotary disconnect uses fuse type CF with a robust selector handle for clear on/off indication and fast, controlled isolation. Business Impact: this reduces eye-witness misoperation and shortens maintenance windows, lowering the risk of arc flash exposure and unplanned outages. Application: ideal for motor control centers, service panels, and equipment shelters where safe, decisive disconnects are required in demanding environments. Feature: The device is rated for 600 V and 100 A in a two-pole configuration, delivering substantial short-circuit withstand and dependable interrupt capability. Business Impact: supports high-current loads with consistent interrupt performance, improving protection for feeders and motors and aiding uptime commitments. Application: suitable for industrial feeders, machine drives, and line-side isolations in manufacturing lines and process plants. Feature: CE marking confirms compliance with European safety directives, and the NEMA 4P enclosure offers weatherproof protection against dust and water in a range of environments. Business Impact: enables installation across indoor/outdoor environments with regulatory compliance, reducing audit findings. Application: appropriate for outdoor installations, wash-down areas, and harsh factory floors where environmental protection is essential. Feature: Dimensions list 11.8 in length, 10.8 in height, 9.84 in width, and a weight of 6 lb, enabling straightforward compatibility checks during panel retrofits. Business Impact: simplifies space planning, reduces custom fabrication, and speeds procurement with known form factors. Application: fits retrofit projects and new panels with constrained depth and mounting space. Feature: Compatible with Eaton Bussmann series protection strategy and CF fuse compatibility, paired with a defined selector handle for reliable operation. Business Impact: reduces spare parts complexity and standardizes maintenance routines across facilities, lowering lifecycle costs. Application: ideal for system integrators and OEMs deploying Bussmann CF fuses within control cabinets, switchgear enclosures, and panel boards in manufacturing, material handling, and processing industries.

FAQs
Begin by verifying panel space and mounting dimensions (11.8 in x 10.8 in x 9.84 in, 6 lb). Mount the enclosure to a rigid backplane, connect the incoming and outgoing conductors to the two-pole terminals, and ensure the selector handle is accessible for quick operation. Confirm 600 V, 100 A ratings align with your panel’s bus structure, then perform a full functional test with the CF fuse in place.
The device is rated for 600 V and 100 A in a two-pole configuration, with a NEMA 4P enclosure for environmental protection. It uses fuse type CF and includes a selector handle for manual operation. These ratings support reliable isolation for feeders, motors, and power distribution in industrial panels.
Yes, the ER4P-100CF2SR is CE marked, indicating conformity with European safety directives. It also features a NEMA 4P enclosure suitable for harsh environments, offering durable protection against dust and water ingress in indoor and outdoor installations. This supports regulatory compliance across many industrial facilities.
Common applications include control panels, motor control centers, and power distribution enclosures in manufacturing, processing, and infrastructure projects. The two-pole design and CF fuse compatibility enable reliable isolation for high-current loads, while the CE and NEMA 4P ratings ensure performance in challenging environments and across global sites.
Routine checks should verify that the enclosure remains weatherproof, the CF fuse remains properly seated, and the selector handle operates smoothly. Given the 600 V, 100 A ratings and NEMA 4P enclosure, plan for periodic inspections in outdoor or wash-down areas and keep a standard spare parts inventory aligned with Bussmann CF fuses for quick replacements.
