Wiring diagram of the control circuit of the HUW1-2000 (and above) Circuit Breakers
1) The circuit on the dotted line is wired by the user, which cannot be performed when the optional accessories
are not customized.
2) The accessories such as intelligent controller, undervoltage release, shunt strip, closing electromagnet and
electric operating mechanism shall be connected to different power sources respectively when the voltages are
different.
3) Undervoltage release must be directly connected to the power supply of the main circuit, with the highest
working voltage not exceeding its rated working voltage. When the working voltage of the main circuit exceeds its
rated working voltage, it needs to be isolated from the main circuit by a transformer.
4) The three-position indication function of the drawer seat is only optional for the drawer circuit breaker.
Note: For the wiring type of independent six normally open and six normally closed of auxiliary switch, perform
wiring adjustment at the space according to the user's order function requirements.
