Circuit breakers are an important part of an electrical system, and the IELHK112-26767-11-V is no exception. They are designed to provide on-off electric power controls for protection against over-currents, short circuits, and electrical failures.

The IELHK112-26767-11-V has a rated voltage of 500V and is able to carry a maximum of 1,000A. It has a working voltage range of 400V-580V and a working frequency of 50-60Hz. It is a 3-pole breaker and features an adjustable tripping current of 6 to 12 times its rated current.

The application field for the IELHK112-26767-11-V mainly includes residential, industrial and commercial buildings. It is suitable for short circuit and overload protection for power distribution systems, control circuits, and lighting circuits. It is also suitable for preventing frequent starts of the motor, thus ensuring normal operation and extending the life of motors.

The working principle of the IELHK112-26767-11-V is quite straightforward. In the event of an over-current or short circuit, the breaker isolates the circuit, cutting off the electricity supply and preventing further damage from occurring. The over-current is detected internally by the breaker’s built-in sensing device, which in turn triggers the release mechanism and trips the circuit breaker. Once the fault is cleared, the breaker can be reset, restoring power to the system.

To further ensure safety, the IELHK112-26767-11-V has various additional features, such as adjustable tripping mechanism, reset lockout, spring latch closure, and adjustable tripping time. This helps to ensure that the breaker responds quickly to an overload or short circuit, and prevents it from being reset too soon.

The IELHK112-26767-11-V is a great choice for a variety of applications. Its robust construction and adjustable features make it an ideal choice for industrial and commercial use. It is designed to provide reliable protection against over-currents, short circuits, and power failures, ensuring safe operation and minimal downtime.
