Introduction of LEGXF66-36874-2-V Circuit Breaker

Circuit breakers are electrical devices that are used to protect against dangerous electrical conditions and sudden surges in current. The LEGXF66-36874-2-V circuit breaker is a two-pole, type-D, short time thermal-magnetic circuit breaker with Class CC/Q (1) terminal type and UL489 (2) complaint. It is designed specifically to improve safety and protect electrical equipment from overcurrents.

Application Field of LEGXF66-36874-2-V Circuit Breaker

The LEGXF66-36874-2-V circuit breaker is ideal for a wide range of applications such as residential, commercial and industrial settings. It can be used for lighting, heating, air conditioning, motor circuits, air conditioners and other electronic equipment. Additionally, because it is designed for both AC and DC systems, it can be used for all types of circuits found in the home, office or industrial premises. Furthermore, it is UL489 listed and Type D rated, which makes it suitable for use outdoors.

Working Principle of LEGXF66-36874-2-V Circuit Breaker

The LEGXF66-36874-2-V circuit breaker features a sophisticated tripping mechanism based on thermal-magnetic technology. This tripping mechanism is designed to activate in the event of an overcurrent or an over-voltage. This is done by constantly monitoring and measuring the current flowing through the circuit. When the flow exceeds the pre-set quantities, the bimetal strip within the device warps in response and activates the tripping device. In thermal mode, the current limitation is based on the current-time characteristics. The thermal mode is intended to protect against serious but short duration overloads and is activated when the current’s peak value exceeds the nominal value for a predetermined amount of time. In the magnetic mode, the current limitation is based on the current-state characteristics. This mode is intended to provide protection from short circuits and is activated instantaneously as soon as the current exceeds the nominal value. The LEGXF66-36874-2-V circuit breaker’s rating is 630A/125VAC and 3600A/250VAC with an interrupting capability of 100kA and a power rating of 20kW at 600VAC. The overcrrent rating is adjustable by an external screw and its trip time delay is adjustable, ranging between 0.4 and 4 seconds.

Conclusion

The LEGXF66-36874-2-V circuit breaker is a two-pole, type-D, short time thermal-magnetic circuit breaker designed specifically to improve safety and protect electrical equipment from overcurrents. It is ideal for a wide range of applications, such as residential, commercial and industrial settings. In addition, the current limitation is based on the current-time and current-state characteristics. Thus, the LEGXF66-36874-2-V circuit breaker is a reliable and effective device for protecting the home, office and industrial premises against dangerous electrical conditions and sudden surges in current.
