Circuit breakers are those devices in electrical systems that are designed to automatically shut down operations during an overload or an excess current in a circuit. They are a key component of any electrical system and often serve as the basis for determining safe and effective operations. This article will focus on the SU3D60UC application field and working principle.

The SU3D60UC is a three-pole circuit breaker intended for use in low-voltage and medium-voltage applications. It is suitable for a wide range of applications, including motor control, lighting, and appliance protection and is available in a variety of ratings, such as 2 A, 10 A, 20 A and 40 A. This type of circuit breaker is designed to protect electrical circuits from overload and short-circuit conditions, as well as providing isolation for maintenance.

The SU3D60UC circuit breaker features a guaranteed breaking capacity of 10 KA, which is suitable for many of the applications mentioned above. It also has an adjustable trip current settings to accommodate different loads, as well as an integrated ground fault protection. The breaker also features a push-button reset that allows for easy recovery from trip conditions.

The working principle of the SU3D60UC is based on a heat-dissipation system. The breaker has two heating elements, which are fused together. In normal operation, these two elements dissipate the heat generated during the operation of the breaker, preventing it from over-heating. In the event of an overload or short-circuit, the heating elements will increase the temperature to a point where the circuit breaker will trip, stopping the flow of electricity.

In addition to its thermal protection, the SU3D60UC also offers a range of protection features. These include a wide range of trip settings, adjustable trip current, and a sensor that will detect arcs or bimetallic elements that can cause over-heating. The breaker is also designed to withstand rapid temperature changes and provide protection from short circuits and overloads.

The SU3D60UC is suitable for a range of applications and is ideal for any circuit that is subject to frequent overloads. Its wide range of protection features, adjustable trip settings and integrated ground fault protection make it a suitable option for any circuit protection application. The breaker’s adjustable trip current and heat-dissipation system ensure it provides the highest level of protection for any system, making it a reliable and safe option for any application.
