Circuit breakers are devices used to protect electric circuits from damage caused by power overloads or short circuits. They are one of the most important components of any electrical circuit and are essential for the safe operation of modern electrical systems. The SU2D25UC is a circuit breaker specifically designed for installation in high voltage circuits up to 25kV, and is ideal for applications such as power substations, power generation and distribution, and motor control.

This breaker features a two-pole operation for high voltage disconnection and a single-pole operation for low voltage operation. The trip unit is OfComp-approved and complies with UL 489 testing requirements. It is designed to provide reliable circuit protection in the event of an overload or short circuit and is rated for up to 25kV. The breaker also features a single-phase thermal overload protection, which helps to prevent overcurrent and undervoltage situations.

The SU2D25UC circuit breaker also features a double-break, double-throw (DBDT) contact arrangement, allowing it to be used in both single-pole and two-pole applications. This configuration allows for the breaker to be used in both high voltage and low voltage scenarios. The Breaker includes a reset button for manual resetting and a trip-free design for automatic resetting.

The SU2D25UC circuit breaker works by detecting an overcurrent or undervoltage condition in a power circuit and automatically opening the corresponding contacts. This is achieved through the use of a thermal sensing element, which is connected in series with the load. When the load current exceeds a pre-set level, the thermal element will activate, causing the circuit breaker to open the contacts on the high voltage side of the circuit.

The SU2D25UC also offers a number of additional features, such as automatic switch-off and an adjustable current setting that allows users to set the trip level to suit their specific application. This breaker is one of the most reliable circuit protection devices available and is designed to provide years of service and reliable performance.

The SU2D25UC circuit breaker is a high quality piece of equipment and is ideal for applications where high voltage and low voltage protection are both required. It offers excellent protection and reliability in a wide range of applications and is backed by a comprehensive warranty.
