32A AC Fuse Holder

CNKA 32A ac fuse holder Introduction

China's leading supplier CNKA provides a 32A AC fuse holder, which is an electrical equipment designed to disconnect circuits when the current exceeds the specified limit. The fuse holder uses its own heat to melt the fuse components after prolonged overload. This is an effective current protection solution widely used in high and low voltage distribution systems, control systems, and various electrical equipment to protect circuits from damage caused by short circuits and overcurrent. The 32A AC fuse holder is one of the most commonly used protective devices in the industry.

CNKA 32A ac fuse holder Structural characteristics

A fuse consists of three main components: the fuse, the housing, and the support. The fuse is crucial for determining the melting characteristics. The material, size, and shape of the melt have a significant impact on these characteristics. Molten materials are divided into two categories: low melting point and high melting point. Low melting point materials, such as lead and lead alloys, have lower melting points and higher electrical resistivity, resulting in larger cross-sectional dimensions, making them only suitable for fuses with low breaking capacity.

On the contrary, high melting point materials such as copper and silver have higher melting points and lower electrical resistivity, which can produce smaller cross-sectional melts, making them ideal choices for high breaking capacity fuses. Melts can take on different shapes, such as filamentous or strip-shaped, and modifying these shapes can significantly affect the melting characteristics. Fuses have a series of melting characteristic curves, making it easy to choose according to specific protection requirements for various applications. They are commonly used in high and low voltage distribution systems, control systems, and electrical equipment, playing a crucial role in preventing short circuits and overcurrent.

Closed fuses are divided into two types: filled fuses and unfilled fuses. Filled fuses are usually composed of square ceramic tubes filled with quartz sand and internal melt, with strong breaking ability, making them suitable for circuits up to 500V and 1kA. In contrast, unfilled fuses wrap the melt in a sealed cylinder, providing slightly lower breaking capacity. These are applicable to power systems or distribution equipment operating below 500V and 600A.
