Circuit breakers, defined as devices whose purpose is to protect a circuit from being damaged by an over-current, are some of the most widely used protective devices in industrial, commercial and residential electrical systems. The BR3D4UC family of circuit breakers has been designed for medium voltage and low voltage applications.

The BR3D4UC circuit breaker range offers solutions for a wide range of applications, from circuit protection for main breaker schemes to distribution switchgears and molded case switches (MCC). It features a wide range of interrupting ratings from 15kA up to 150kA, and a variety of construction types, such as three-pole, four-pole and drawout construction.

The BR3D4UC is a medium voltage vacuum interrupter with an embedded media system. It combines a reliable and robust operating mechanism with an arc quenching system to permit the interruption of current and voltage waves. The vacuum technology employed in the BR3D4UC is the standard in medium voltage circuit breakers, offering both a compact design and superior performance.

The BR3D4UC circuit breaker uses a trip mechanism to open and close the contacts when needed. The trip mechanism is designed to react quickly to an over-current or short circuit in the circuit, allowing for fast and reliable interruption. The trip mechanism is connected to the operating coil on the breaker, which is energized when a fault is detected. When the operating coil is energized, it causes the trip assembly to move, which in turn opens or closes the contacts.

The BR3D4UC is designed to provide superior arc quenching performance and reliable operation. The breaker uses an arc quenching chamber to suppress the dangerous arc produced when the contacts open or close. The chamber works by rapidly dissipating the thermal energy produced by the arc, preventing the temperature in the chamber from rising and releasing toxic gases into the air.

The BR3D4UC circuit breaker also features a monitoring system, which is used to ensure that the breaker is functioning correctly. The monitoring system uses a variety of sensors to detect changes in operating conditions, such as changes in voltage or current levels. The system will then set off an alarm or trip the breaker to protect the circuit from further damage.

In addition to its reliability and arc-quenching capabilities, the BR3D4UC family of circuit breakers also offers cost-effectiveness and flexibility. The cost-effectiveness is due to the wide range of ratings, interrupting capabilities and construction types, while the flexibility is provided by the monitoring capability and the ability to be used in both medium and low voltage applications.

The BR3D4UC family of circuit breakers is ideal for a wide range of applications, including industrial, commercial and residential electrical systems. The robust construction, reliable operation, arc quenching and monitoring capabilities all combine to ensure maximum protection.
