Its pistol handle and CF fuse-type configuration offer straightforward operation and safe, compliant isolation in both indoor and outdoor environments. When retrofitting, ensure mounting fits standard enclosure footprints and supports three-pole configurations for balanced operation.
The device is rated for 100 A continuous current and 600 V maximum. This rating governs the maximum load and fault current it can safely interrupt, influencing selection for motor loads, control circuits, and feeders. The CF fuse-type compatibility provides selective protection and faster fault clearance, while the NEMA 3R enclosure ensures ingress protection suitable for harsher environments, enhancing overall system reliability.
Yes. The EN closure is rated NEMA 3R, which offers rain and corrosion resistance suitable for outdoor use and damp indoor environments. CE marking confirms compliance with European safety standards. This combination supports reliable operation in facilities exposed to dust, humidity, or incidental weather exposure, reducing the need for additional enclosure upgrades and facilitating safer maintenance access.
ER3R-100CF3PB carries CE Marking and a NEMA 3R enclosure rating, indicating compliance with European safety requirements and suitability for outdoor or protected indoor installations. Its three-pole, 100 A, 600 V specification aligns with typical industrial power distribution and motor control applications, while the CF fuse type and pistol handle support standardized safety procedures and maintenance workflows in industrial facilities.
The unit's rugged Bussmann enclosure and CF fuse integration provide predictable performance with minimal maintenance. The CE/3R rating enhances accessibility in global projects, reducing support complexity. Benefits include faster fault isolation, reduced downtime, and safer de-energization during servicing, all contributing to lower total cost of ownership and improved productivity for control panels and distribution cabinets.
