Circuit Breakers

2D16UM Application Field and Working Principle

Circuit breakers are widely used in any type of electrical circuit, large or small. They are designed to protect circuits from overloading, short circuits, and other circuit faults. This article will discuss the application fields and working principle of the 2D16UM circuit breaker.The 2D16UM is a 2-pole, 480V, 10-50A miniature circuit breaker from Swedish manufacturer ABB. It is used primarily in residential and light commercial electrical systems, where it offers overload and short circuit protection for lights and motors. It is also often used in small industrial applications where overload and short circuit protection is needed.The 2D16UM uses Thermal-Magnetic technology to provide circuit protection. It features two different mechanisms for tripping circuits: a thermal trip mechanism and a magnetic trip mechanism. The thermal trip mechanism works by detecting an increase in temperature inside the breaker due to increased current flow. When the temperature surpasses a predetermined limit, the thermal trip mechanism trips the breaker, interrupting the current and providing overload protection. The magnetic trip mechanism works by detecting an increase in current flow, and when it surpasses a predetermined limit, the magnetic trip mechanism trips the breaker, interrupting the current and providing short circuit protection.In addition to providing circuit protection, the 2D16UM also has a range of features to improve usability and safety. It features an Indicator Light which alerts the user when the circuit is tripped, or when the breaker has been manually tripped to cut the power. It also features a Locking Device, which prevents the breaker from being reset until the cause of the trip has been identified and corrected.The 2D16UM is a reliable and easy-to-use breaker, making it a popular choice in residential and industrial applications. Its thermal-magnetic technology provides effective overload and short circuit protection, while its indicator light and locking device improve safety and usability. The 2D16UM is a great choice for most applications where a high-performance circuit breaker is needed.
