Product Description
LYUM1L Series moulded case circuit breaker (hereafter reffered to as simply breaker), whose insulated voltages 800V, suitable for conversion and starting a motor not frequently in the circuitof 50Hz AC, rated working voltage 400V, rated working current up to 690A, The breaker have overload, short circuit and under-voltage protection device, which protects the circuit and power equipment against damage.
According to level of breaking capacity of rated maximal short circuit, the breaker can be classified into two types, Type M(Relatively High breaking type), Type L(High breaking type), Such breaker possesses the features such as compactness, high breaking capacity, short arc-cover and shock resistance, etc.
The breaker can be installed vertically (upright) as well as horizontally (crosswise).
