Circuit Breakers

A circuit breaker is an electrical device designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Traditionally, a fuse was used for this purpose, but circuit breakers are now mainly used.

3130-F120-P7T1-W14QR7-3A Application Field and Working Principle

The 3130-F120-P7T1-W14QR7-3A circuit breaker is a series of short circuit protection devices used in low voltage distribution networks. It is mainly used for the overload and short circuit protection of various types of electrical equipment.

The 3130-F120-P7T1-W14QR7-3A circuit breaker is an electromechanical device that operates automatically to either close or open a circuit. Its operation is based on either a current sensing element or thermal element. When the current passing through the circuit exceeds the breaker\'s rating, an electrical force is created which trips the breaker. In the case of rising thermal elements, an increase in temperature trips the breaker.

The 3130-F120-P7T1-W14QR7-3A circuit breaker is equipped with a three-position switch that offers three protection settings. The first setting is used for normal operation. During this setting, the circuit breaker will react to an over-current or short circuit and open the circuit. The second setting is used for unbalanced current protection. In this setting the circuit breaker will be sensitive to an imbalance in the current. Finally, the third setting offers overload protection. This will reduce the risk of an over-current and cut off power to the equipment.

The 3130-F120-P7T1-W14QR7-3A circuit breaker can be used in various applications including industrial, commercial, and residential applications. It is most commonly used for general lighting circuits, air conditioners, office equipment, heating systems, and other electrical appliances. It is a reliable and cost-effective device that is capable of preventing damage to both people and equipment.
