IELHK11-30299-352-V

Circuit Breakers

IELHK11-30299-352-V is an auto-reclosing circuit breaker. A circuit breaker is a safety device in electrical circuits that interrupts the power supply in case of a fault, such as short circuit or overload. Instead of fuses, circuit breakers are used as the protection device in order to avoid any further damage caused by a current overload or short circuit. The IELHK11-30299-352-V circuit breaker is used to provide an automatic response to faults in electrical systems. Automatic resetting helps to reduce downtime and the need for manual intervention in the case of an outage.

Application Field

The IELHK11-30299-352-V is commonly used in industrial electrical systems, such as in manufacturing, data centers, and other commercial applications. In manufacturing operations, the IELHK11-30299-352-V is used to protect circuits and equipment against overvoltages, undervoltages, overcurrents, and short circuits caused by faulty electrical installations. In data centers, the IELHK11-30299-352-V is used for protection of critical components and systems, reducing the risk of catastrophic failure due to overload.

Working Principle

The IELHK11-30299-352-V circuit breaker operates using an electromagnet and two sensors. The electromagnet is activated when an AC power is applied to it. When the current in the circuit reaches a pre-determined limit, the electromagnet pulls the SPD (short for Suitable Protection Device) switch to trip position. The SPD switch then cuts the power to the circuit, and the circuit breaker enters into the tripping mode. In the tripping mode, the sensors sense the current and reset the circuit breaker automatically. Once the fault has been eliminated, the circuit breaker can be reset and the circuit will be reconnected.

The IELHK11-30299-352-V is known for its high performance and reliable protection. It is a low cost solution compared to other circuit breakers and is designed for high current applications, which makes it a popular choice for many industrial and commercial applications.
