FAQs
To install the WCF100RN, insert the cube fuse into a compatible Bussmann Series fuse holder or panel with standard mounting. The WCF100RN is a 3.01 inch long, 1 inch wide, finger-safe CUBEFuse with dual elements. It carries a 100 A, 690 VAC rating and a 30 kA interrupting capability, simplifying quick replacements without sacrificing safety.
Key specifications include a 100 A amperage rating, 690 VAC maximum voltage, and a dual-element current-limiting design for fast fault interruption. It is a Class CF fuse, non-indicating, with a 30 kA interrupting rating and a glass-filled PES body. It is CE marked and RoHS compliant, suitable for general industrial protection.
Yes. The WCF100RN carries CE marking and RoHS compliance, indicating adherence to European safety, health, and environmental standards. This helps ensure regulatory alignment for panel builders and end users. When integrating into a machine or control system, verify wiring, enclosure ventilation, and replacement intervals to maintain ongoing compliance.
Suitable for motor feeders, control circuits, MCCs, and protection in industrial automation panels, the WCF100RN provides reliable short-circuit protection for 100 A circuits. Its fast-acting dual-element design limits current quickly, reducing arc energy and downtime. Its Class CF format fits standard Bussmann fuse bases found in many industrial installations.
By using the WCF100RN, you gain improved selectivity and faster fault isolation, reducing downtime and maintenance costs. The durable glass-filled PES body withstands industrial environments, while its finger-safe construction lowers injury risk during replacements. Combined with RoHS and CE compliance, it helps minimize regulatory risk and spare-part holding costs in large deployments.
