FAQs
Yes. The ER4P-100CF2SB is specified for 600 V systems and two-pole operation, designed to fit typical industrial control panels and motor control centers. Its NEMA 4P enclosure provides weather and dust protection, while the selector handle supports safe manual operation and lockout/tagout practices. Ensure mounting dimensions and enclosure clearances meet your panel design requirements.
Key ratings include 600 V maximum voltage and 100 A current rating with a two-pole configuration. The device supports CF fuse-type protection and complies with CE marking. The NEMA 4P enclosure rating offers environmental protection, making it suitable for both indoor and outdoor installations. For critical loads, verify coordination with compatible fuses and circuit protection schemes.
Industries with demanding manufacturing, packaging, and process control environments benefit from this unit. It is well-suited for motor control centers, machine control panels, and safety-isolated feeders in spaces where rugged enclosure protection and reliable isolation are required. The CF fuse option supports selective protection in feeders, improving overall system reliability.
The ER4P-100CF2SB is CE marked, indicating compliance with applicable European standards. It features a NEMA 4P enclosure rating for protection against the elements, dust, and water ingress. These certifications support use in regulated environments and simplify cross-border deployments, while providing assurance of build quality and reliability.
CF fuse integration reduces the number of separate components in the protection scheme, which simplifies stocking, maintenance, and field upgrades. By providing targeted protection for feeders and compatible with standard Bussmann series catalogs, it can lower downtime and spare parts costs. This translates to improved uptime, faster serviceability, and a favorable ROI over the equipment life cycle.
