Circuit Breakers

Circuit breakers are electrical switches used to protect overloading of electrical current in a circuit. If too much current is drawn, the circuit breaker will trip to open the circuit and break the flow of electricity. This prevents overheating and even electrical fires. One of the most commonly used circuit breakers is the LELPK111-1REC5-32039-1-V.

Application Field

The LELPK111-1REC5-32039-1-V is a single pole, thermal magnetic circuit breaker that is suitable for use in residential, commercial, and industrial applications. This device can be used in a variety of applications, including breaker panels, distribution boards, switchboards, motor control centers, and more. The thermal magnetic operation protects the circuit in the event of overloads, while the magnetic-only function can be used for short circuit protection.

Working Principle

The LELPK111-1REC5-32039-1-V is a thermal magnetic type circuit breaker. It has a thermal element which monitors the amount of current flowing through the circuit and is typically set to trip at about 1.5 times the normal operating current. This means that the breaker will trip when the current reaches 1.5 times the normal level, which is usually considered an overload. The device also has a magnetic element which monitors the amount of current when the breaker is tripped. This is typically set to detect short circuit current, which is usually much higher than the normal operating current, and is typically set to trip at about 5-6 times the normal operating current.

In operation, the thermal element is the first line of defense in protecting the circuit. When the current reaches 1.5 times the normal operating current, the thermal element will detect this and activate the breaker, which will trip open the circuit. The magnetic element then takes over, and will remain active even after the thermal element has cooled down. If the current is still too high, the magnetic element will trip the circuit breaker and the circuit will remain open until the current has returned to a safe level.

The LELPK111-1REC5-32039-1-V circuit breaker provides reliable, comprehensive protection for a variety of residential, commercial, and industrial applications. The device combines a thermal element and magnetic element to provide both overload and short circuit protection, ensuring that the circuit is protected from both common and rare power disturbances. With its versatile design and high performance, the device is an ideal solution for a wide range of applications.
