IELHK111-1-61-100.-A-01-V

Circuit breakers are integral components in electrical and electronic systems. They are designed to protect against various electrical hazards, such as short-circuits, overloads, and electric shocks. The IELHK111-1-61-100.-A-01-V circuit breaker is a type of circuit breaker designed for medium and high-voltage application. Its main functions are to interrupt the electric current flow in case of a fault and isolate the equipment from the power source.

The IELHK111-1-61-100.-A-01-V circuit breaker is suitable for circuit protection in electrical installations, such as power systems, motor control systems, and electronic equipment. It is designed to operate in temperatures ranging from -40°C to +40°C and humidity up to 98%. It is suitable for both indoor and outdoor applications. The breaker is designed withstanding short-circuit current up to 100 kA and operates under systems rated from 12 to 24 kV.

When switching the breaker off with a manually operated switch, the current will be interrupted within 0.3 seconds. The breaker can be operated manually or remotely. If the breaker is used in an automatic control system, then a power source must be connected to the control circuit. The output contact of the breaker is designed for loads up to 3-20A. The contact resistance is very low and it is designed to provide a high-performance switch to ensure reliable operation.

The working principle of the IELHK111-1-61-100.-A-01-V circuit breaker is quite simple. When the current reaches the breaker\'s rated limit, the bimetal strip heats up, and the increase in temperature bends it. This bending action trips an internal mechanism which releases a latch and disengage the contact terminals. This action breaks the current connection and prevents any further current flow. Since there is no physical connection between the terminals, the risk of electric shock is minimized. The bimetal strip then cools down and its shape returns to its original position.

The IELHK111-1-61-100.-A-01-V circuit breaker is a reliable and efficient device for medium and high voltage applications. It provides protection from electrical hazards, such as short-circuits and overloads, and it is designed to operate in a wide temperature and humidity range. The breaker has low contact resistance and is designed withstanding short-circuit currents up to 100 kA. Its working principle is based on a simple bimetal strip heating up and bending when the current reaches the rated limit, thus interrupting the connection.
