Circuit breakers are essential safety devices in electrical power systems. IALHK11-39381-10 is one kind of ultrashort-trip, high-speed, high breaking capacity, high inherent short circuit resilience, and low temperature rise circuit breaker. It is widely applied to protect power system, power plants, substations, nonresidential, and industrial installations.

IALHK11-39381-10 applies an electronic coil to trip the breaker automatically in case the supply current is too high. The optical fibres and amplifiers of the IALHK11-39381-10 have high speed and high sensitivity. It could quickly detect any abnormal increase of current in the circuit and send out the trip signal.

The working principle of IALHK11-39381-10 is based on its electronic coil. When the current in the protected load rises above the pre-set value, a computer-aided relay circuit is activated, and the electric energy is released to unset the breaker rapidly. This circuit works by responding to the current and breaking the internal parts of the breaker. The breaker is then released and the circuit breaks.

IALHK11-39381-10 also ensures the reliability of the breaker’s response, as a monitoring method for the tripping of the breaker. This two-stage protection system consists of an internal temperature, current sensor, and over-current protection, which are all connected to the monitoring system. The internal temperature and current limitation can be preset in software.

The safety of the installations within the protected circuit is ensured by the stop/guard of the breaker. The two internal contacts, mechanical and electrical, are working together to ensure this safety. When the main contacts across the breaker open, the current stop/guard will separate the electrical circuit, thereby preventing any further increase in current.

In addition, IALHK11-39381-10 has the capacity to work in extreme environmental conditions and be used in high-voltage applications. It is also intrinsically safe, as it offers the highest level of safety, reliability, and efficiency.

Overall, IALHK11-39381-10 is a safe, reliable, and robust circuit breaker. It is the perfect choice for those looking for a high-performance and cost-efficient circuit breaker that can be used in a variety of applications. Its high speed, short-trip, and low temperature rise features make it an ideal choice for protecting electrical systems, power plants, substations, nonresidential, and industrial installations.
