Circuit breakers are vital safety components in any electrical system. They protect important electrical lines, semiconductor devices, and other electrical hardware from high currents or excessive temperatures. The IDGS1-34721-20 is one type of circuit breaker that is used in a range of applications. This article will explain the application field and working principle of the IDGS1-34721-20 circuit breaker.

The IDGS1-34721-20 is a universal, thermal circuit breaker designed for use with AC power circuits that operate between 200V and 600V. It is suitable for a variety of medium- and high-voltage applications, such as wind turbines, industrial power systems, automotive power distribution systems, and solar photovoltaic arrays. It is particularly suitable for locations with high humidity, as its features and components are corrosion-resistant.

The IDGS1-34721-20 uses the basic principles of thermal circuit breaker operation. This involves a thermal element and an over-current triggering mechanism. The thermal element is made of a special alloy that has a high thermal expansion coefficient. The thermal element is connected to a resistor and a switch. When the current loading on the circuit exceeds the rated current, the thermal element expands, which causes the resistor to short out, thus disconnecting the circuit.

The over-current triggering mechanism works by using a bimetallic strip. This strip acts like a spring, with one end connected to a spring and the other to a contact point. When the current loading on the circuit increases, the bimetallic strip deflects, causing the spring to compress and the contact point to open. This then trips the circuit breaker and disconnects the circuit.

The IDGS1-34721-20 circuit breaker also has a number of additional features designed to provide better protection. It has an adjustable current range, meaning that the circuit breaker can be set to trip when the current loading on the circuit exceeds a certain value. It also has an overload protection feature, which will trip the circuit breaker if the current loading on the circuit exceeds its maximum capacity. Finally, it also has a short circuit protection feature, which will trip the circuit breaker if the circuit has an excessive short circuit.

The IDGS1-34721-20 is a reliable and safe circuit breaker, capable of protecting circuits from excessive current and temperature. It is suitable for a variety of medium- and high-voltage applications, and its features and components ensure excellent corrosion resistance. It is also easy to install, adjustable, and provides overload and short circuit protection. The IDGS1-34721-20 is a versatile circuit breaker that is well suited to a variety of applications.
