Modern circuit breakers are devices designed to protect electrical systems from overloads, which occur when too much current passes through the wires of a circuit. Such events can be caused by multiple factors, including faulty wiring, excessive voltage, short circuits, or inrush current. In these situations, the circuit breaker trips and turns off the power to the circuit, thereby preventing further damage to the electric system. One such device is the CELHPK11-33572-200, a type of molded-case circuit breaker (MCCB). In this article, we will discuss the CELHPK11-33572-200’s application field and working principle.

Application Field

The CELHPK11-33572-200 is a molded-case circuit breaker designed for the low voltage power distribution market. It is suitable for residential, commercial, and light-commercial applications, including lighting, air conditioning, heating, motor circuits, protection of thyristor drives, etc. The device is also suitable for industrial applications such as panel buildings, switchboards, machine tool applications, power factor correction, and UPS-type systems.

Working Principle

The CELHPK11-33572-200 is a three-pole, two-pole shared trip circuit breaker with a thermal-magnetic trip unit. The thermal-magnetic trip unit works by using a bimetal strip, which is either heated or magnetically affected by excess current passing through the circuit. When the bimetal strip is deformed, it trips the breaker, thus turning off the electricity to the circuit and preventing further damage.

The CELHPK11-33572-200 has adjustable tripping settings, which allow the user to set the amount of current the breaker can handle before it trips. This setting is useful in ensuring that the breaker only trips in the event of a dangerous overload, and not in normal operation. The device is also equipped with an alarm bell that sounds when the breaker trips, as a warning to the user.

The CELHPK11-33572-200 is highly reliable and designed to exceed safety requirements. Its robust design ensures that it can handle up to 200 thousand operating cycles, and its isolator enables the user to deactivate the breaker without having to disconnect the power input.

In addition, the device is rated for high inrush current protection and has a unique current limiting device, which adjusts the breaker tripping time to fit the actual load situation. This ensures that the breaker trips only when it is absolutely necessary, and not due to minor fluctuations in current.

In conclusion, the CELHPK11-33572-200 is a reliable, highly capable circuit breaker designed for use in a variety of residential, commercial, and light-commercial applications. It is equipped with a thermal-magnetic trip unit and adjustable tripping settings, allowing users to customize the breaker’s trip time. The device is rated for high inrush current protection and high operating cycles, and its isolator allows for easy deactivation. This mold-case circuit breaker provides a reliable and safe solution for power distribution needs.
