Circuit breakers are electrical equipment that are responsible for the safety of distribution systems. According to the standards and regulations established by the International Electrotechnical Commission (IEC), they are used for breaking, making, isolating and short-circuiting electrical circuits.

LEGHF66-1-62-12.0-A-01-V is a type of molded case circuit breaker (MCCB). As a key element of power distribution, the LEGHF66-1-62-12.0-A-01-V circuit breaker is a device specially designed for interrupting and re-establishing power circuits easily and quickly. The device is fully compliant with the requirements of IEC60947-2, and features a complete set of overcurrent, undercurrent, short circuit, earth leakage protection functions, as well as motor overload, phase unbalancing and reverse phase protections.

The application field of LEGHF66-1-62-12.0-A-01-V circuit breaker mainly includes power factor compensation, power transmission and distribution, electric motors, lighting control circuits, and other critical loads. The working principle of the device is that when the circuit comes across faults, such as overcurrent, undercurrent, short circuit, earth leakage, or others, the breaker will trip and break the circuit.

Generally, the LEGHF66-1-62-12.0-A-01-V circuit breaker has three poles with its rated voltage up to 690VAC (50/60Hz) and breaking capacity up to 600A. The device is also equipped with load limit indicators to reflect the real-time load status of the circuit, allowing users to easily monitor and control. On top of that, the circuit breaker is also connected with various accessories, such as earthing terminal for protection, remote switch for control, and trimmer resistor for calibration.

The LEGHF66-1-62-12.0-A-01-V circuit breaker is recognized as an effective device in power distribution systems due to its functional range and comprehensive protection capability. The product is highly reliable and easy to install, which greatly reduces the electrical wiring cost.
