Eaton Specification Sheet - ER4X-100CF3PB
Enclosed three-pole design with CF fuse compatibility provides complete circuit isolation of all three phases in a single operator action. This reduces arc exposure and minimizes the risk of accidental energization during maintenance or changeovers on motors, conveyors, and feeders. The approach accelerates safe lockout/tagout procedures and helps meet industrial safety standards with confidence. The pistol-style handle enables fast, one-handed operation with a clear on/off indication, supporting intuitive field use. In practice, technicians experience quicker reset after maintenance cycles and fewer mis-operations during panel isolation, improving overall uptime and reducing maintenance-window costs in high-throughput manufacturing lines. Rated for 600 V and 100 A, the ER4X-100CF3PB supports common industrial feeders and motor control circuits without oversized components. Its three-pole configuration guarantees simultaneous disconnection of all lines, improving fault isolation, protecting downstream devices, and simplifying coordination with protective relays and fusing strategies in control panels. Built with a NEMA 4X enclosure, this switch resists corrosion, dust, and wash-down conditions, making it suitable for harsh factory floors and outdoor installations. The rugged construction reduces corrosion-driven maintenance and extends service life in challenging environments, helping facilities maintain compliance with environmental protection requirements. CE marking and alignment with Bussmann series catalogs streamline regulatory compliance and procurement. The compact yet sturdy footprint simplifies panel integration, spare parts planning, and cross-compatibility with standard CF fuse kits, reducing total cost of ownership while preserving traceability across global sites and multiple product families within the Eaton catalog. Dimensions and weight support practical installation planning: roughly 11.8 in length, 10.8 in height, 9.84 in width, and about 6 lb. The predictable footprint enables consistent mounting in standard electrical enclosures and allows technicians to plan clearance and wiring routes with confidence during upgrades or replacements.

FAQs
The ER4X-100CF3PB is designed for panel mounting in standard electrical enclosures. It features a three-pole, enclosed configuration with overall dimensions of approximately 11.8 in L, 10.8 in H, and 9.84 in W, plus a 6 lb weight. When planning installation, verify opening size and space within the panel for service clearance, and consult the datasheet for exact mounting hole patterns and recommended mounting practices.
This switch is rated for 600 V and 100 A, with a three-pole configuration that disconnets all three phases simultaneously. The result is improved fault isolation, reduced arc exposure, and safer maintenance workflows for three-phase motor feeds and conveyors. The CF fuse compatibility further supports coordinated protection strategies within industrial control panels.
Yes. The unit features a NEMA 4X enclosure, providing resistance to corrosion, dust, and wash-down conditions. This makes it appropriate for factory floors subject to frequent cleaning, outdoor installations, and other challenging environments while maintaining reliable isolation and operator safety in routine maintenance and emergency servicing.
The device is CE marked and built to meet rigorous environmental and safety expectations for industrial equipment. It also carries a NEMA 4X enclosure rating and is compatible with Bussmann series CF fuse protection schemes, which aids in regulatory compliance, global procurement, and standardized maintenance across sites.
The pistol-style handle enables quick, one-handed operation, reducing setup time during maintenance and inspections. Three-pole, reliable isolation minimizes mis-wiring risks, while CF fuse compatibility simplifies component replacements. Collectively, these features reduce downtime, shorten maintenance windows, and lower total cost of ownership across plant sites.
