W58-XB1A4A-7

Circuit breakers are protective gear designed to protect electrical systems from over-voltage, short circuits and over-current. The W58-XB1A4A-7 is a type of circuit breaker. It is a miniature breakers, meaning it is designed to protects circuits less than 15 amperes. It is a single pole, thermal and magnetic breakers.

The application field of W58-XB1A4A-7 includes the protection of lines in electric circuits, such as terminals, lighting fixtures, cables, communication lines and equipment, power lines, motor cradles, electric furnace controllers, etc. Moreover, this circuit breaker provides a variety of applications in the industrial sector such as continuously energizing and re-energizing of motors, electric welding machines, transformers, and other electric equipment. In the home electrical system, the W58-XB1A4A-7 is used to provide security to electrical lines and electric shocks protection for household appliances, in areas such as kitchen, living room, bathroom, etc.

The working principle of the W58-XB1A4A-7 is divided into three parts: mechanical action, thermal action, and magnetic action. In operation, the incoming electricity is sensed by the broken wire contacts, these contacts move linearly, turning the mechanical spring, which tensions and maintains the contacts in a closed state. As the current passes through the contacts, it is broken into two, and the mechanical tension is released, thus driving the contacts which, in turn, open the circuit.

The thermal action involves the use of a bimetallic strip. The bimetallic strip is made up of two different materials that have different thermal coefficients. The bending of the strip is related to the temperature increase, due to the passage of current, of one of the materials moving away of the other. This bending causes the opening of the contacts.

Finally, when designing the W58-XB1A4A-7, a magnetic-induced device was added, which operates on the principle of increasing or decreasing the force produced by an electromagnet, depending on the amount of current that passes through the circuit breaker. When the current is too high, the force generated is greater than the mechanical tension, thus driving the contacts and opening the circuit.

In conclusion, the W58-XB1A4A-7 is a type of miniature circuit breaker designed for single-pole protection of electrical systems from over-voltage, short circuits and over-current. Its application field includes the protection of lines in electric circuits, and industrial sectors such as continuously energizing and re-energizing of motors, electric welding machines and transformers. Its working principle is based three elements: mechanical, thermal and magnetic.
