Introduction

3518P fuseholder is an important product type of the fuseholders which offer ultra-small size, high fault current withstand and reliable performance. It is designed for the highest level of industrial automation and bridging between different electrical modules.

Features

3518P fuseholder features a double circuit bridge configuration that can handle high current circuits, and a stacked design that enables near-direct connection from the inlet to the outlet. It features integrated thermal shutoff and a fully sealed design. The current rating is up to 30 A and the breaking capacity is up to 20 kAc. It\' s material is copper alloy and the operating temperature is -20°C to +85°C.

Applications

3518P fuseholder is widely used in many areas, such as automotive, home appliances, power equipment, industry and military. It can be used in all kinds of circuit boards, including high frequency boards, printed circuit boards and heat sinks.

Working Principle

3518P fuseholder utilizes a bridged connection between the two poles of the fuse holder body. This bridge-type connection has high-voltage withstand capability and can be used to protect fuses, terminals and other components from any over-currents.As current flows through the fuse holder, it is constantly monitored by a current sensor. When the current reaches or exceeds the rated current of the fuse holder, the current sensor sends a signal to the circuitry of the fuseholder, which activates the thermal shutoff feature. This thermal shutoff will then shut off the current completely or by half, thus protecting the circuit from any further over-currents.

Conclusion

3518P fuseholder is an important product type of fuseholders, offering small size, high fault current withstand and reliable performance. It is widely used in the automotive, home appliances, power equipment, industry and military fields. Moreover, its working principle is based on a bridged connection and a thermal shutoff feature to protect the circuit from any over-currents.
