Introduction

The R25400-3CR fuseholder is a type of fuseholder designed to protect electrical circuits from overloads. It is made from a robust metal enclosure, which encloses two terminals for the connection of the incoming power and the outgoing load. It also contains two trigger springs, which act when the circuit receives too much current. The purpose of this article is to discuss the application field and working principle of the R25400-3CR fuseholder.

Application Field

The R25400-3CR fuseholder is designed to be used in low-voltage systems, primarily those rated up to 250V AC, or up to 60V DC. It is offered in either single- or double-pole configurations, depending on user requirements. The current ratings of this fuseholder range from 0.5A up to 10A.

The application field for this fuseholder is wide and varied. It is used in a range of industries and applications, including automotive, appliance, industrial control and communication systems. This versatile fuseholder is also suited to a wide variety of other electrical applications, such as HVAC systems, PC boards, transformers and LED lighting.

Working Principle

The working principle of the R25400-3CR fuseholder is relatively simple. When the circuit is functioning within its normal range, the two trigger springs remain in their normal positions. However, if the circuit is overloaded and exceeds its current rating, the trigger springs actuate and cause the fuseholder to shut down the current flow through the circuit. This prevents the circuit from being damaged by the excessive current.

The trigger springs are further reinforced by the robust metal enclosure, which protects the contacts from dust, debris and other outside elements. This feature ensures that the circuit remains protected even when conditions become rough.

Conclusion

The R25400-3CR fuseholder is a versatile and reliable fuseholder suitable for a range of low-voltage applications and industries. Its robust metal enclosure and trigger springs combine to make it an effective method of protecting electrical circuits from overloads. It is able to shut down the current flow quickly and effectively, ensuring the circuit remains safe and secure.
