HMKM1E series electronic molded case circuit breaker (hereinafter referred to as the circuit breaker) is applicable to AC 50Hz (or 60Hz), its rated insulation voltage is 800V, and its rated working voltage is
The circuit with voltage of 690V and below and rated working current of 800A is used for infrequent switching and infrequent motor starting. The circuit breaker has overload long time-delay inverse time, short circuit short time-delay inverse time
Time limit, short circuit short delay time limit, short circuit instantaneous and undervoltage protection functions, residual current protection (optional), phase failure protection functions (optional) can protect lines and power equipment from damage,
The circuit breaker protection features are complete and accurate, which can improve the reliability of power supply and avoid unnecessary power failure. The "Z" type control has a communication interface, which can be "four remotes" to meet the control requirements
Requirements for the heart and automation system.
According to the rated limit short-circuit breaking capacity, circuit breakers are divided into M type (high breaking type) and H type (high breaking type). The circuit breaker has small volume, high breaking capacity
Short flashover, anti vibration, etc.
The circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).
The circuit breaker has the isolation function, and its corresponding symbol is "".
The circuit breaker shall not reverse the incoming line, that is, only 1, 3 and 5 are allowed to be connected to the power line, and 2, 4 and 6 are allowed to be connected to the load line.
