Circuit breakers are devices designed to interrupt the current flow when a fault is detected. LEG66-37357-5-V is a type of circuit breaker that is commonly used in industrial applications, such as control systems and automotive applications. In this article, we will discuss the application field and working principle of the LEG66-37357-5-V circuit breaker.

LEG66-37357-5-V Application Field

The LEG66-37357-5-V circuit breaker is a three-pole device that is UL, CSA, and CE approved for use in industrial and commercial applications. It is suitable for applications that require low voltage protection, such as control and automation systems. It is also suitable for use in applications such as automotive, residential, and commercial lighting systems. The rated current and breaking capacity of the device make it suitable for use in many application fields. Additionally, the LEG66-37357-5-V meets strict international standards, making it suitable for use in hazardous locations.

LEG66-37357-5-V Working Principle

The LEG66-37357-5-V circuit breaker is an electrically operated protective device. When it detects a fault in the circuit, it interrupts the current flow automatically. The device contains two main components: the switching mechanism and the protective element. The switching mechanism is used to switch the circuit off while the protective element is responsible for sensing faults in the circuit.

The LEG66-37357-5-V is a thermal-magnetic device, which means that it responds to both thermal and magnetic forces. The device has an internal thermal element and an internal electromagnet. When a fault is detected, the thermal element senses the increased temperature and opens the contacts, interrupting the circuit\'s current. The internal electromagnet also responds to the fault, creating an attractive force that keeps the contacts open.

To reset the device, the operator must manually reset the trip flag that is located on the front of the breaker. Once the fault has been cleared, the trip flag can be reset, allowing the breaker to be reset and the circuit to be energized again.

Conclusion

The LEG66-37357-5-V is a three-pole circuit breaker that is UL, CSA, and CE approved for use in industrial and commercial applications. It is suitable for use in applications that require low voltage protection, such as control systems and automotive applications. The device is a thermal-magnetic device, which means that it responds to both thermal and magnetic forces. The breaker can be manually reset once the fault has been cleared, allowing the circuit to be energized again.
