Motor-driven operating mechanism (MOD)
The motor-driven operating mechanism is an accessory used for easy and reliable remote automatic
breaking and making. The electric operating mechanism of Ex9M6 is factory assembled inside the
circuit breaker, which is applicable for electronic type circuit breaker and disconnecting switch.
Protection class: IP40
Function:
Button controlled circuit breaker breaking and making
* Motor breaking and making or manual breaking and making optional
* Indication for breaking and making and free release
*
*
*
Operation
Use manual/auto knob to select operation type:
Auto
Switch the manual/auto knob to “auto” position, achieving connection and disconnection of
circuit breaker through remote “breaking or making” signal.
Manual
Switch the manual/auto knob to “manual” position, achieving connection and disconnection of
circuit breaker by rotating the operating handle.
The normal automatic operation of the electric operating mechanism and the reliable
connection and disconnection of circuit breaker are only guaranteed when the control voltage
is ≥85%Us.
Applications
Local electric operation, centralized operation, automatic control
* Normal/backup power transfer, or switching to backup power, optimizing energy cost
* Unload and reconnection
* Synchronous coupling

Features
Modbus communication module (COM22)
COM 22 module is the interface module for the communication between electronic type moulded
case circuit breaker and bus system, it is used for communication and relay control output. Used with
Modbus-RTU communication protocol, this module can easily connect with on-site bus equipment and
provide three or four remote functions.
Technical parameters:
Rated voltage: AC230V or DC24V (error±15%)
Communication type: RS485 (Modbus-RTU protocol)
Contact capacity: AC250V/3A; DC30V/3A
Operating status indication: LED indication
Number of working station: 1
Installation
Use DIN 35-7.5 standard rails
