LFJ104001C Fuseholders

Fuseholders are devices used to secure and protect fuses for low-voltage electrical equipment. The LFJ104001C is one of the many fuseholders on the market, designed with versatility and reliability in mind. It is a compact, lightweight, and powerful device that can sustain fault currents up to 300A.

Application Field

The LFJ104001C is suitable for a wide variety of applications, such as power distribution cabinets, operational cabinets, control cabinets, and electric power cabinets. With its slim design, this fuseholder can be installed in cabinets that are as narrow as 5MM wide without compromising its safety. This fuseholder is UL508 approved and can be used in both enclosed and open cabinets. In addition, it can be used in Class A, B, and C equipment when the incoming power is 250V AC or less.

Working Principle

The LFJ104001C works by enabling the circuit to be disconnected from the power source when an overload or short-circuit is detected. This fuseholder is made of thermoplastic material with high dielectric strength. Its body and lid are insulated and able to withstand temperatures ranging from -40°C to 85°C. It consists of two parts: the terminal and the fuse holder. The terminal is made of copper and has a shut-off capability of up to 7000A, enabling efficient and reliable electrical connections. The fuse holder is designed to accommodate standard 5x20mm fuses and features a knob that allows the user to adjust the tension of the contact. This ensures that the fuse is securely held in place.

Safety Design

The LFJ104001C is designed with safety as a top priority. It features dual fuse mounting to prevent accidental disconnection, and its ergonomically designed knob prevents short-circuiting. In addition, the contact pins are designed to minimize arcing and ensure optimal performance with maximum protection. The fuseholder also features a visual and audible alarm to alert the user when the fuse needs to be replaced, and its enclosure is shatterproof and scratch-resistant.

Conclusion

The LFJ104001C fuseholder is an ideal choice for applications involving low-voltage electrical equipment. It is versatile, lightweight, and powerful, and is designed to provide maximum protection with minimum arcing. Its safety features make it ideal for enclosed and open cabinets, and its thermoplastic insulation makes it suitable for installations of up to 250V AC. It can withstand temperatures ranging from -40°C to 85°C, and its ergonomic knob prevents short-circuits and accidental disconnection.
