Circuit breakers are devices that are used to protect circuits and other electrical devices from excessive currents. The 2D2UM (Two Direction-Two Unipolar Method) is a type of circuit breaker that is specifically designed for Ultra-Violet (UV) applications. This article will discuss the application field and working principle of 2D2UM.

Application Field

The 2D2UM is primarily used in industrial ultra-violet (UV) applications, which require protection from hazardous electrical conditions. It can also be used in other applications where the 2D2UM’s high rated current and fast transient response would be beneficial. These applications include medical equipment, motor control systems, lighting systems, and many others. The 2D2UM’s fast transient response property also makes it suitable for use in pulse-width modulated (PWM) driven systems.

Working Principle

The working principle of the 2D2UM is based on a unique two-direction, two-unipolar method of current detection. This method allows the 2D2UM to instantly detect both high and low current events that occur within the circuit, and quickly respond by tripping the breaker. The two-direction, two-unipolar method of current detection consists of two sensing elements; a differential voltage transformer and a bi-directional current transformer.

The differential voltage transformer determines both high and low current events, while the bi-directional current transformer determines both positive and negative current events. Once a current event is detected, the 2D2UM’s control unit is triggered and the breaker is tripped. The primary advantage of the 2D2UM over other circuit breakers is its fast response time. It can detect and trip within 10 ms, compared to traditional circuit breakers which can take uqp to 30 ms.

In addition, the 2D2UM offers advanced features, such as electronic thermal memory, lockout memory, and self-test capability. These features provide additional protection from electrical hazards and provide improved reliability. The 2D2UM is also designed to withstand high surge currents. It can handle up to 10kA for 10 cycles, and is designed to exceed the IEC standards for surge protection.

Conclusion

The 2D2UM is a type of circuit breaker specifically designed for industrial ultra-violet (UV) applications. It uses a unique two-direction, two-unipolar method of current detection, which allows it to quickly detect high and low current events, and trip the breaker within 10 ms. The 2D2UM also offers advanced features, such as electronic thermal memory, lockout memory, and self-test capability. It is designed to handle high surge currents and exceed IEC standards for surge protection.
