1C15UR circuit breakers are widely used in fields where voltage control and high starting current are essential components, such as motor and high power transmission. The 1C15UR series circuit breakers are designed to divide the electrical current flowing through an electrical circuit into equal parts, limiting the current flow to a predetermined level. The principle of operation of the circuit breaker is based on the Joule-Thomson effect or the kinematics of a mechanical switch.

Function of 1C15UR Circuit Breakers

The major function of 1C15UR circuit breakers is to break and make an electrical circuit in a controlled manner to protect electrical systems and equipment from overcurrent. By only allowing a certain amount of current to pass through, circuit breakers can prevent cables from overloading and provide voltage protection to components, ensuring the safety and reliability of the system.

Applications of 1C15UR Circuit Breakers

1C15UR circuit breakers are commonly used in several applications, including:

• Lightning protection : 1C15UR circuit breakers can be used as lightning protection devices to prevent damage to the electrical systems caused by lightning.
• Industrial motor drives : The 1C15UR series circuit breakers are suitable for motor drives, due to its wide operating temperature and wide voltage range.
• Distribution systems : The 1C15UR circuit breaker is highly reliable and suitable for use in power distribution and industrial control applications.
• High power transmission : The 1C15UR series circuit breakers are designed to be used in high power transmission applications, providing reliable switching, excellent current interruption and superior performance.

Working principles of 1C15UR Circuit Breakers

The working principle of 1C15UR circuit breakers is based upon two distinct effects – the Joule-Thomson effect and mechanical switch operation. The Joule-Thomson effect is a temperature-dependent effect where the resistance of a compressed gas is proportionally related to the temperature. As the pressure is increased, the temperature increases and the resistance increases. This quadratic relationship between pressure and temperature is what allows the circuit breaker to limit the current flowing through it.

The second effect of 1C15UR circuit breaker operation is the motion of a mechanical switch, which is connected to the pressure regulator. When the current flowing through the circuit breaker reaches a predetermined level, the amount of pressure generated by the current shift causes the mechanical switch to move and open the circuit, thus breaking the electrical connection.

The 1C15UR series circuit breakers are designed with modular construction that allows for customized installations, as well as over-current and voltage protection. They are available in various models, with different voltage ratings and capability to handle high start-up current.

In summary, the 1C15UR circuit breakers are ideal for applications that require a reliable protection system with high start-up current requirements. They provide protection from over current, voltage fluctuations, and safety when dealing with high power transmission applications. The 1C15UR circuit breakers are designed with modular construction to allow for customized installations, as well as to provide reliable operation, current interruption, and superior performance.
