RDQ3NMB 125 amp MCCB Types Of Changeover Switch Automatic Transfer Switches
RDQ3NMB automatic transfer switch is a disruptive innovation to the traditional dual power ATS design, by organizing chief engineers investing R&D for two years, finally launched at the end of 2014, it has 8 sizes, which are 63A, 125A, 250A, 400A, 630A, 800A, 1000A, 1250A. With B type intelligent controller and LED display. Reliable mechanical interlock device and electrical interlock protection, avoid two MCCB close at same time; Controller power supply and power source sampling power separate from SCM control system, overcome EMU from hardware design. Controller can be take down and mounted at panel door with data cable connection. AC-32B utilization category per IEC/EN 60947-6-1 standard.
RDQ3NMB Innovated mechanical interlock design:
 | The push handle adopts adjustable slider structure design, has more wide circuit breaker's ON/OFF travelling distance, makes the production process more simple. |
 | Optimized cam transmission mechanism design ensures the reliability of mechanical interlock and at same time makes the mechanical life more than 10000 times. |
 | Adopt mechanical positioning detect structure, make the ATS switching more accuracy and reliable during fire linkage. |
OEM/ODM Service
Support using customer brand MCCB as main switch.
