0451015.NR

Fuses

0451015.NR is the designation for a type of fuse class 2, indicating that it is a fast-acting fuse designed for secondary circuit protection that is typically used in DC circuits with voltages less than 60V and while large current surges that demand quick reaction times. This particular type of fuse is compatible with a wide range of circuits and is built to flawlessly tackle sudden current surges, with the ability to withstand an overload up to three times the rated current.

Application Field

0451015.NR fuses are used for various applications, such as circuit protection on medical devices, power tools, battery chargers, and other small electronic appliances. As they are small in size, they are easy to install and maintain, and they provide a wide range of protection. Furthermore, these fuses have high resistance to sulfur and moisture, as well as are made in accordance with MIL-F-23419B and UL 248-14 standards.

Working Principle

When a current exceeding the rated current flows through the circuit, the element in the fuse rapidly melts and quickly isolates the equipment without damaging it or causing further risks to the user. In general, when the rated current flows, the fuse does not act, but when this is exceeded, it immediately reacts. It is extremely important to select the right capacity for the fuses used in currents. If the current exceeds the rated current, the fuse will melt the element, breaking the circuit and protecting the components in the circuit.

The fuses have color coding that indicates the rated current that they can handle. The red-coded fuse has a maximum rated current of 5 amps, and the blue-coded fuse can handle currents up to 10 amps. This makes it easy to identify the right fuse for each application.

Features and Benefits

0451015.NR fuses are well-recognized for its many advantages, including small size, fast reaction time, reasonable protection level, and wide operating temperature range (-65 degrees Celsius to 125 degrees Celsius). They also provide stability in the presence of surges in both current and voltage.

The major advantage of 0451015.NR fuses is, by far, its ability to accommodate fault currents quickly and disconnect the circuit with minimal circuit drop. Since the fuse has high-speed, high-de-rating capability, it provides protection on almost any DC circuit, regardless of the current or voltage, making this type of fuse an ideal choice for situations where current inrush or possible overcurrent responses need to be controlled.
