1170-22-4A

Circuit breakers are an important part of electrical systems, and 1170-22-4A is one of the many types of circuit breakers in use. This device is designed to provide protection against electrical faults in circuits of low and medium voltage. Its primary function is to disconnect power to the circuit when an overcurrent or short circuit condition occurs. The 1170-22-4A circuit breaker has several unique features that make it ideal for use in numerous applications.

Application Field

The 1170-22-4A circuit breaker is suitable for use in places such as lighting systems, commercial and industrial buildings, telecommunications, retail and residential areas, etc. It is designed and rated for protection of up to 600 volts. This means it can be used for standard three-phase systems, as well as single-phase systems. It also offers protection for motors and transformers, making it suitable for a variety of applications.

It is also designed for limiting the opening of a circuit breaker when an overload current occurs. This is beneficial in preventing sudden power outages due to electrical faults, which could potentially cause severe damage to the equipment. Additionally, it is designed to open quickly when a short circuit occurs, limiting damage in the event of an electrical fault.

Working Principle

The 1170-22-4A circuit breaker is designed to protect electrical circuits when an overload or short circuit occurs. It operates on an electromagnetic principle, where a sensing coil is used to detect when a dangerous amount of current is present.

When the sensed current exceeds a certain set level, the 1170-22-4A circuit breaker will cause an adjustable solenoid to pull the breaker tripping mechanism into the open position. This causes the electrical circuit to open, reducing the possibility of severe damage from an override of too much current.

The 1170-22-4A circuit breaker is also designed to reset itself when the overload condition is corrected. The reset is a slow process, so as to prevent further overload. It also helps to minimize the amount of time that the circuit is inactive in the event of an electrical fault.

In addition to providing protection from overload and short circuit conditions, the 1170-22-4A circuit breaker also provides protection from environmental hazards such as lightning, surges, and other transient effects. This device is designed with a glass body, which is filled with nonflammable insulation and sealed to prevent access to the contacts.

Conclusion

The 1170-22-4A circuit breaker is a reliable device that offers protection from overloads, short circuits, and other electrical hazards. It is suitable for use in many applications where protection from electrical faults is necessary. Its slow reset feature helps to prevent further damage to equipment in the event of an electrical fault, while its electromagnetic design helps to limit the amount of power that is present in an electrical circuit.
