Introduction

Fuseholders are electrical components used to secure and terminate fuses in an electric circuit. The LR250301PR fuseholder by Schneider Electric offers a secure and reliable connection point for fuse-based circuit protection. This comprehensive and innovative design enables the user to make quick and efficient connections with a minimum of assembly time.

Application Field

The LR250301PR by Schneider Electric is designed to meet the needs of the most demanding applications in terms of strength, durability and reliability. It is suitable for the protection of home wiring, power systems, industrial machinery, and other environmentally-sensitive applications. In addition, the LR250301PR is certified for use in Class I and Class II, Division 2 hazardous locations.

Construction

The LR250301PR is designed to provide a secure and reliable connection under almost any electrical or environmental conditions. The unit consists of a plastic body with an external copper alloy conductor and an internal contact spring. The body is made of UL94-V0 rated materia, providing flame retardancy and impact resistance. The external copper alloy conductor provides excellent electrical performance and the internal contact spring reduces installation time and cost.

Working Principle

The LR250301PR works on the principle of thermal expansion. When the current in the circuit exceeds a predetermined value, the temperature of the fuse and fuseholder will begin to rise, causing the contact spring to expand. This expansion forces the contacts apart, breaking the circuit and protecting it from further damage. Once the circuit has cooled, the contacts will reconnect, allowing the circuit to function again.

Conclusion

The LR250301PR fuseholder by Schneider Electric is an innovative and reliable solution for the protection of home wiring, power systems, industrial machinery, and other environmentally-sensitive applications. Its external copper alloy conductor and internal contact spring provide a secure and reliable connection, while its UL94-V0 rated material ensures flame retardancy and impact resistance. The unit works on the principle of thermal expansion, allowing it to break the circuit when the current exceeds a predetermined value and reconnecting it once the circuit has cooled.
