Circuit Breakers

A circuit breaker is a protective device designed to break an electrical circuit if an overload or short circuit happens. This helps protect the circuits from damage due to excessive current flow. Most modern circuit breakers are designed to detect fault currents, shut down the circuit, and subsequently trip an alarm or signal if the fault persists.

The 229G-3-32086-16 is a type of circuit breaker used for medium-voltage applications. It is a magnetic trip circuit breaker typically used for secondary feeder applications including motor control centers, switchgear, distribution boards, generator sets, and other industrial/commercial applications. The 229G-3-32086-16 has a rated voltage of 8 kV, a current rating of 160 A, and a breaking capacity of 50 kA.

Application Field and Working Principle

The 229G-3-32086-16 is designed for use in AC systems up to 8 kV. It can be used for both indoor and outdoor applications in such environments as industrial plants, commercial buildings, hotels, and hospitals. Its operating range is between 65 percent of its rated current and its maximum current rating, which is 160 A. The breaker is designed to open as soon as a fault is detected and is trimmed to shut down workers and equipment when necessary.

The 229G-3-32086-16 is based on a magnetic trip principle, which means that when a fault is detected, the circuit breaker reacts using a magnetic force. This force then triggers the trip mechanism within the breaker, breaking the circuit. The trip mechanism operates by using an electromagnet and a trip shunt. When a fault is detected, the electromagnet magnetizes the trip shunt, breaking the circuit and cutting off the power supply.

The 229G-3-32086-16 is designed with an adjustable trip coil. This allows users to set the trip current level to their desired values. Different trip levels are also available for the breaker and can be changed depending on the application. In this way, users can program the device to prevent it from tripping due to low-level faults.

Overall, the 229G-3-32086-16 is a reliable circuit breaker for medium-voltage applications. With its adjustable trip coil and customizable trip levels, the 229G-3-32086-16 is well suited for both industrial and commercial applications.
