Circuit breakers are important components of the electrical system, playing the role of ensuring safe operation of electrical equipment. IULBXK1-34021-5 is a commonly used air-break circuit breaker, with a rated voltage of 3.6KV and a rated current of 2000A. This breaker has a wide range of applications due to its excellent performance.

In general, IULBXK1-34021-5 circuit breakers are applied to protect the power transmission and distribution system from overcurrent and short circuit faults. This breaker is a high-efficiency and reliable device designed to protect motor, transformer and other equipment in the circuit. When used in system maintenance and energy saving, it also helps to minimize power loss due to short circuits.

The working principle of IULBXK1-34021-5 is based on the current flowing through its contact. When the normal current passes through the contact, it is switched on. But when the current flowing through the contacts exceeds the specified value, the magnetic flux produced by the current will be sufficiently increased, thus pushing the arc extinguishing chamber of the breaker\'s operating mechanism.

After the arc extinguishing chamber is moved, the contacts of the breaker will be separated immediately to shut down the circuit. This action is completed in about 0.15 seconds to cut off the current transferred by the contacts, thus achieving the effect of circuit protection. In addition, when the fault condition is cleared, the operating mechanism will recover its original position and the contacts will return to the initial on-state.

No matter whether it is used in power supply or power transmission, IULBXK1-34021-5 circuit breaker plays an important role in ensuring the safe operation of the electrical system. It is designed with high performance and high reliability, and the working mechanism is robust and reliable. It can effectively ensure safe power supply and protect equipment from overload or short circuit damage.
