Fuses are devices that are used to open or close electrical circuits and are designed to break the circuit when an overload of electricity is detected. 049402.5NRHF is one such type of fuse used for a variety of applications.

04402.5NRHF is a type of time-lag fuse that is typically used to protect lighting circuits, small motors, and entire households from an overload of electricity. This type of fuse features a time-delay element that delays the action of the fuse, allowing small inrush currents to pass before the fuse opens the circuit.

04402.5NRHF fuses are able to be used in ultra-long circuit connections and are part of the NRH series of vacuum capacitance fuse products, making them a popular choice for both residential and commercial applications. Being UL recognized ensures that they are up to safety standards, and their versatility makes them attractive to customers due to the wide range of applications they can be used in.

The 049402.5NRHF fuse consists of two parts: a fuse element and a fuse-end. The fuse-end is snapped onto the fuse element which is typically connected to the circuit. The fuse element operates the overload current sensing mechanism, which then triggers the interruption of the circuit.

The 049402.5NRHF fuse is designed with a capacitive element and two conducting pieces, with a voltage connected and current flowing between them. This creates a time-lag which allows for the fuse to detect any overload and interrupt the circuit in order to protect it. When a sustained overload occurs, the heat generated by the current melts the two conducting pieces, separating them and creating an open-circuit break.

Due to its time-lag design, the 049402.5NRHF can also be used in sensitive circuitry, and in applications which have a startup surge. This is due to the fuse’s ability to detect and respond to transient inrush currents that are detection is nearly instant.

The 049402.5NRHF fuse has numerous advantages, such as its small size which allows for more efficient circuit protection and convenience. Additionally, its ability to detect and respond to transient inrush currents makes it ideal for a range of high-intensity commercial and residential applications.

In conclusion, the 049402.5NRHF is a type of time-lag fuse that provides overload protection for sensitive circuitry, lightning circuits, and entire households. It is UL recognized, making it safe for use in a variety of applications, and its small size makes it a convenient choice. Its ability to detect and respond to even transient inrush currents makes it an ideal choice for both residential and commercial applications.
