Introduction

F03B250V1-1-2A is an electrical specialty fuse with a breaking capacity up to 125A. It is a fast-acting type fuse characterized by small size and high breaking capacity. It is widely used in the industry of household appliances, power distribution system and other power-related fields.

Application

F03B250V1-1-2A is suitable for circuit isolation and short circuit protection in the industry of household appliances, power distribution system and more. This device is designed for protecting electrical circuits and systems from overloads or short circuits. It can be used on most of the AC circuit and DC circuit of dc 48V.

The application field and working principle of F03B250V1-1-2A can be exemplified in the following conditions. First, when the current going through the fuse exceeds the rated current, the heat generated by the current will cause the fuse element to melt. Second, when the temperature inside the fuse reaches a certain value, there will be a pressure on the fuse holder body and the fuse element will break. Third, when the voltage across the electrical circuit exceeds the rated voltage, the fuse element will break instantly.

Working Principle

When the current going through the fuse exceeds its rated current, the heat generated by the current will cause the temperature inside the fuse to rise. When this temperature reaches a certain value, a pressure will be exerted on the fuse holder body, which, in turn, will break the fuse element. As soon as the fuse element breaks, the current flowing through the circuit will be interrupted, which will protect the electrical circuit from overload.

The breaking capacity of F03B250V1-1-2A is up to 125A and it can be used in 50 and 60 Hz AC circuit or in DC circuits up to DC 48V. This fuse has a high melting point and its melting time is short, which ensures reliable and fast circuit protection.

Advantages

The advantages of the F03B250V1-1-2A fuse include:

• Fast-acting with small size: The small size of the fuse means that it can easily be installed in tight spaces and its fast-acting characteristics ensure reliable and fast protection.
