Overview

The Mersen RF35 is a fast-acting, Class H ferrule fuse designed for general-purpose applications where available short-circuit currents do not exceed 10,000 amperes. This fuse operates at a maximum voltage of 250VAC and a current rating of 35A. It is part of Mersen's RF series, which are suitable for replacement using RL series die-cut zinc replacement links, available from 2 to 600 amperes across 31 ratings. The RF35 fuse is manufactured in the USA and adheres to stringent quality standards. Its ferrule design ensures secure connection within compatible fuse holders. This product is ideal for protecting electrical circuits from overcurrents and short circuits in various industrial and commercial settings. For applications requiring higher short-circuit current ratings, Mersen offers alternative fuse solutions. Ensure proper selection based on system voltage and fault current levels. The Mersen RF35 provides reliable overcurrent protection for a wide range of equipment. Its fast-acting characteristic ensures rapid interruption of fault currents, minimizing damage to protected components. Consult Mersen's comprehensive catalog for detailed specifications and application guidance. SKU: RF35.
