The 7S-EL-DC110V electric operating mechanism enables motorized tripping and closing of switchgear switches, status signal feedback, and interlocking with switchgear anti-misoperation logic, supporting distribution automation control.
• Drive Unit: DC motor, gear/linkage transmission mechanism, matched to the make/break torque of switchgear switches;
• Control Unit: PCB control board (including interlock logic, communication module), terminal block;
• Auxiliary Components: Status feedback contacts, mounting bracket, secondary wiring cables.
• Original Equipment Compatibility: Specifically designed for Siemens SIMOSEC, 8DA, and other switchgear series, with fully matched mechanical/electrical interfaces;
• Intelligent Control: Integrated RS485 communication, stall protection, and EMC design, supporting remote/local operation switching;
• Convenient Wiring: Pre-configured plug-in wiring units simplify secondary circuit connections and adapt to distribution automation systems.
• Switch Actuation: Enables motorized closing/opening of load switches and grounding switches;
• Status Feedback: Outputs remote signaling for switch status (open/closed), coil energization, etc.;
• Safety Interlocking: Interfaces with switchgear anti-misoperation logic to prevent errors (e.g., grounding switch operation prohibited during circuit breaker closing).
| Parameter Category | Specification Range |
