04941.25NRHF Application Field and Working Principle

Fuses are electric safety elements designed to protect cables and electrical components from fire and thermal hazard caused by overload or short circuit. 04941.25NRHF is a type of fuse with UL98 and CSA certification. It has many applications in the aerospace, telecommunications, marine and defense industries.

The 04941.25NRHF consists of a copper alloy fuse link, two silver-plated copper alloy ferrules, two silver-plated copper alloy clamps and a plastic outer case. The copper alloy fuse link is designed to provide thermal and physical protection from overcurrents. The silver-plated copper alloy ferrules provide electrical contact to the surrounding areas, such as the power supply, to ensure continuity of current. The two silver-plated copper alloy clamps are designed to hold the fuse link and case together. The plastic outer case provides insulation to protect other parts from possible electrical shocks.

The 04941.25NRHF has a working principle of heat-conductive disconnection. When an overload or short circuit occurs, the fuse link will heat up quickly. The heat caused by the fuse link will be conducted to the ferrules and clamps, and then to the other parts of the device. The heat will cause the fuse link to deteriorate and eventually break at the weakest point, causing the device to be disconnected from the power supply.

The 04941.25NRHF is an ideal safety device for any industry that requires reliable and easy-to-replace fuses. It has a superior current rating of up to 500A and has the ability to withstand overloads and short circuits for extended periods of time. The silver-plated copper alloy components ensure good electrical contact and the plastic outer case ensures safety from electrical shocks. The 04941.25NRHF helps to protect expensive components and cables from fire and thermal hazards.
