FAQs
The WCF50RN is a compact cube fuse with a 2.13 in length, 1.13 in height, and 1 in width, designed for standard panel enclosures. Ensure appropriate mounting clearance, compatible busbar connections, and proper alignment with the cube fuse holder. Its finger-safe design reduces handling risk during maintenance, and its dual-element construction supports reliable protection without frequent nuisance trips.
The WCF50RN carries CE marking and RoHS compliance, aligning with European safety and environmental standards. Its Class CF designation indicates current-limiting protection suitable for fast fault interruption, while finger-safe construction minimizes operator exposure. This combination supports regulatory audits and helps maintain safe, compliant electrical installations.
Yes. The WCF50RN is rated for up to 690 VAC and provides a 50 kA interrupting rating, enabling effective protection against short-circuit faults on industrial power and control circuits. The 50 A amperage rating matches common motor and control loads, helping ensure selective protection and minimizing downstream disruption.
Industries such as automotive, packaging, process automation, and general manufacturing benefit from its robust Class CF current-limiting protection, dual-element design, and finger-safe features. It is well-suited for control panels, motor starters, and power distribution enclosures where reliability, regulatory compliance, and easy maintenance are priorities.
Plan for periodic inspection of panel protection, maintain a stocked inventory of spare WCF50RN units, and replace after any fault event to restore protection. The non-indicating design requires attentive fault documentation, and the fuse’s standard dimensions simplify retrofit projects and rapid substitution without changing cabinet layouts.
