IELK1111-27320-9-V

IELK1111-27320-9-V Application Field and Working Principle

Circuit breakers are devices designed to interrupt an electric current when a circuit becomes overloaded or short. This prevents a circuit from becoming damaged due to high current, and also protects people and equipment from electric shock. The IELK1111-27320-9-V circuit breaker is a DC rated device, meaning it can be used in either direct current or alternating current circuits.

Application Field

The IELK1111-27320-9-V circuit breaker is designed for use in high-voltage DC applications, such as solar power systems and other electric power systems. It can be used to protect both the system components and equipment from overcurrent, overvoltage, and short circuit. The IELK1111-27320-9-V circuit breaker is self-resetting, meaning it will automatically reset itself after a fault, allowing it to be used without the need for manual resetting.

Working Principle

The IELK1111-27320-9-V circuit breaker works on a simple principle. When an overcurrent or overvoltage is detected, a bi-metal strip or bimetal thermal switch inside the circuit breaker is activated, causing a mechanical contact to open. This cuts off the electric current, preventing it from flowing. When the overload or excess voltage is decreased, the bimetal thermal switch will reset itself, allowing the circuit breaker to be used again. The IELK1111-27320-9-V circuit breaker also has a manual reset switch, allowing it to be reset manually if necessary.

Conclusion

The IELK1111-27320-9-V circuit breaker is a reliable device designed for use in high voltage DC applications. Its self-resetting bimetal thermal switch allows it to interrupt electric current when necessary, without the need for manual resetting. This makes it ideal for use in solar power systems, high voltage electric power systems, and other similar applications.
