Ml series plastic case circuit breaker (circuit breaker for short) is suitable for AC 50Hz (or 60Hz). Its rated insulation voltage is lOOOV (Ml-63 type is 800V, Ml-1600 type is 1140V), and the rated working voltage is 400V/690V (Ml-1600 type is 1140V) and below, with infrequent conversion and operation in circuits with rated operating current up to 1600A.The motor is used for infrequent starting. The circuit breaker has overload, short circuit and under-voltage protection functions, which can protect lines and power equipment from damage.
According to the rated limit short-circuit breaking capacity, it is divided into L type (standard Huai type) and M type (high breaking type).
There is no code for direct operation of the handle; P for electric operation; Z for rotating the handle.
The circuit breaker for power distribution has no code; the protection motor is represented by 2.
According to the number of poles of the product, it is divided into three-pole and four-pole. Among the four-pole products, there are four types of neutral pole (N pole):
Type A: No overcurrent release is installed on the N pole, and the N pole is always connected and does not combine or open with the other three poles.
Type B: The N pole is not equipped with an overcurrent release, and the N pole is combined and opened with the other three poles (the N pole is closed first and then opened).
Type C: The N pole is equipped with an overcurrent release, and the N pole is closed and opened together with the other three poles (the N pole is closed first and then opened).
Type D: An overcurrent release is installed on the N pole, and the N pole is always connected and does not open or close together with the other three poles.
