Introduction

Fuse holders are basically devices used to connect a fuse to an electrical circuit. They are commonly used to protect the circuit against over current and short circuit faults. The H25030-1SEZ is a type of fuse holder manufactured by General Electric. It is designed for use in a variety of applications including lighting and control systems, home appliances, and motor controls. This article will discuss the application field and working principle of the H25030-1SEZ.

Application Field

The H25030-1SEZ fuse holder is designed for use in 120/240VAC single phase applications. It is suitable for use with class CC, F, G and K fuses. It is suitable for various applications such as lighting and control systems, home appliances, motor control center, and general power distribution. It features built-in terminals and a spring-action, quick-connect terminal block that can accommodate up to four terminals. The H25030-1SEZ is designed for maximum safety and reliability. It features a shock-resistant construction and flame retardant thermoplastic housing. This ensures that the fuse holder provides superior protection against accidental short circuits, fire, and other hazards.

Working Principle

The H25030-1SEZ fuse holder works on the principle of overcurrent protection. It is designed to prevent excessive current from flowing through the circuit by ‘blowing’ the fuse if the current reaches a certain level. This is achieved by having an internal set of leads and contacts that, when the current reaches a certain level, one of the leads and contacts will literally melt, thus interrupting the current flow. The H25030-1SEZ also features a trip-free design, meaning the contacts will not reset until the fuse has been replaced. This further increases safety as it prevents the user from reconnecting the circuit if the fuse has left.

Conclusion

In conclusion, the H25030-1SEZ is a type of fuse holder designed by General Electric for use in a variety of applications. It is suitable for 120/240VAC single phase applications and for use with class CC, F, G and K fuses. It features built-in terminals, a spring-action, quick-connect terminal block, shock-resistant construction, and a flame retardant thermoplastic housing for superior protection. The H25030-1SEZ works on the principle of overcurrent protection to prevent excessive current from flowing through the circuit and features a trip-free design for extra safety.
