Circuit Breakers are an essential component of electrical control systems, providing a reliable and safe way to protect systems from electrical shock, overheating, and other potential dangerous conditions. The SU1D32UC is an advanced circuit breaker that offers robust and reliable protection for an array of 3-phase applications. This article will explain the application field and working principle of the SU1D32UC.

The SU1D32UC is commonly used in medium voltage primary networks and distribution boards. It is suitable for installations where the current demand is 250kA at a 25kA short-time current capability. It is capable of both normal and abnormal load current Auto-Reclosing, along with Motor Control and Generator Protection capabilities.

The SU1D32UC is designed to protect motors, generators, and electrical control systems from electrical shock and overloads. This breaker features a thermal-magnetic trip system that works in conjunction with a timer to continually monitor the load current. When an overload or short-circuit occurs, the timer allows the breaker to trip before the current reaches dangerous levels.

The SU1D32UC also provides protection against abnormal conditions such as abnormal transient currents and abnormal voltage (undervoltages, overvoltages, and phase imbalance). The breaker is also self-resetting and can be manually reset in the event of a trip or fault.

The breaker also includes a variety of adjustable Settings that can be adjusted to suit the needs of different applications. These settings include a current/time product setting, a minimum/maximum trip setting, and a voltage/time product setting. These settings can be adjusted to allow for longer protection times, shorter trips, or a combination of both.

The trip characteristics of the SU1D32UC can also be adjusted to provide the optimum protection for any given application. The breaker can be adjusted to trip on either high- or low-currents, as well as low voltage trips and overvoltage trips.

The breaker also features a system diagnostic mode that continuously monitors the breaker operation and can alert operators if there is a fault or trip condition. The diagnostic mode also provides a history of trip events, allowing for quick and easy troubleshooting in the event of a problem.

The SU1D32UC is an advanced circuit breaker, offering robust and reliable protection for a range of different applications. Its adjustable Settings and system diagnostic mode enable it to be personalized for each application, making it suitable for a wide range of conditions and environments. This makes the SU1D32UC a great choice for protecting machinery, motors, generators, and electrical control systems from electrical shock and overloads.
