Circuit breakers are convenient tools used to protect electrical circuits and components from heat, overvoltage, and overload. A SU1D35UC circuit breaker is a type of Miniature Low Voltage Device (MLVD) designed to detect and monitor energy levels across an electrical circuit. It is used to protect the electrical components from damage, isolate electrical circuits, and control the flow of electricity. This article will provide an overview of the application field and working principle of the SU1D35UC circuit breaker.

The SU1D35UC is mainly used for the protection and control of motors, lighting, contactor coils and other low-voltage loads. It can also be used to control power distribution at the secondary level, by isolating the circuit from the main supply whenever a fault is detected. This makes it ideal for use in industrial and commercial applications, particularly those with limited space and where the currents are mainly AC.

The working principle behind the SU1D35UC is the same as all other Miniature Low Voltage Devices. The device monitors current and voltage levels in the circuit, and opens the circuit whenever it detects an overload or excessive current. This prevents the electrical components in the circuit from being damaged by the excess electricity.

One major advantage of the SU1D35UC is its low power consumption. It consumes only 0.68W of power, making it more energy efficient than other similar devices. It also has a current rating of 0.3A, which means it can protect a circuit with a maximum current load of up to 0.3A.

The SU1D35UC also features various protection modes, such as thermal protection, overload protection, short circuit protection, and reverse current protection. These modes ensure safe operation of the device, and ensure that the connected circuit is protected from excessive electrical stress. The device also has a status indication LED, which is used to provide visual indication of the state of the circuit.

Overall, the SU1D35UC is a robust and reliable device for protecting low voltage circuits. It is a relatively small device, which makes it ideal for applications with limited space, and its low power consumption makes it highly energy efficient. The various protection modes ensure that the circuit is protected from overvoltage and overloads, while the status indication LED provides visual indication of the state of the circuit.
