Circuit Breakers

Circuit breakers are electric devices used to break an electrical circuit in case of an overload or short circuit in the circuit. They are typically used in industrial wiring, commercial buildings, and residential wiring. The most common type of circuit breaker is a LELHK11-1-62-15.0-U-01-V, which is designed to protect motors from damage due to overloads.

Application Field

The LEH11-1-62-15.0-U-01-V circuit breaker is mainly used in motor circuits. It can be used with both AC and DC electric motor circuits, and is designed to protect the motor from damage caused by overloads or short circuits. In addition to motor circuits, this circuit breaker is also suitable for use in other circuits where protection from overloads and short circuits is necessary.

Working Principle

The working principle of circuit breaker starts by detecting an overload or short circuit in the circuit. In the case of an overload, the breaker detects the current in the circuit and trips, breaking the circuit and preventing any further damage. Conversely, if there is a short circuit in the circuit, the breaker also trips, breaking the circuit and preventing further damage.

In the case of a LELHK11-1-62-15.0-U-01-V circuit breaker, there is also a thermal trip element that helps to detect an overload even before an excessive current is reached. When excessive current is detected by the thermal trip element, it will cause the breaker to trip, protecting the motor from damage. In both cases, the breaker will reset after the overload or short circuit is cleared.

Advantages

The main advantage of using a circuit breaker such as the LELHK11-1-62-15.0-U-01-V is that it is designed to protect the motor from damage due to overloads or short circuits. Without a breaker, either of these scenarios would likely result in the motor being damaged or destroyed, resulting in costly repairs or replacement. Additionally, the thermal trip element in the LELHK11-1-62-15.0-U-01-V allows it to detect overloads and short circuits before excessive current is reached, providing extra protection for the motor.

Conclusion

The LELHK11-1-62-15.0-U-01-V is a circuit breaker designed primarily to protect motors from damage due to overloads and short circuits. It operates based on detecting overloads and short circuits, and trips the circuit to prevent further damage. The thermal trip element in this particular breaker also helps to detect overloads before excessive current is reached, providing extra protection for the motor. In conclusion, this type of breaker is an important tool for protecting motors in a wide range of applications.
