Complementary Combination Switch
✅ No inrush current,no overvoltage switch
✅ Low Power Consumption and longlife,500000 times
✅ Fast response,<200ms
✅ High EMC protection measures, strong anti-interference capability
- Product Introduction
Jinneng electric Complementary Combination Switch is a new generation of electronic products. There are two types:centralized compensation type and split phase compensation type. The centralized type is used for switching three-phase capacitors, using the"△"connection method.
In the fields of power electronics and reactive power compensation, the Composite Switch specifically refers to an intelligent switching device that integrates thyristors (semiconductor) and magnetic latching relays (mechanical) in parallel, designed exclusively for switching capacitors.

Product features
| Feature | Technical Benefit |
|---|---|
| Zero-cross switching | 1. Voltage-zero closing (capacitor energization) 2. Current-zero opening (de-energization) - Eliminates inrush current (<1.2× rated current) - Prevents switching overvoltage (<1.3× system voltage) |
| Low power consumption | <3W per phase (vs. 8-15W for contactors) |
| Harmonic-free operation | THD<1% (no additional grid pollution) |
| Enhanced EMC | Opto-isolated control signals + EMI filters (surge immunity: 4kV) |
| Seamless integration | Compatible with dynamic VAR compensation controllers (Modbus RTU protocol) |
| Status monitoring | LED indicators for: - Switch position (ON/OFF) - Power status - Fault alerts |

Application
The composite switch is the mainstream and ideal choice for static reactive power compensation, particularly suitable for:
● Conventional power factor correction (PFC) cabinets.
● Applications where load changes are not extremely rapid (cycle times on the order of seconds or more).
● Industrial and commercial projects with high requirements for compensation reliability, equipment lifespan, and operating costs.
● Replacing traditional "contactor + current-limiting reactor" solutions for better performance.
