CHNT NXB Interlock Changeover Circuit Breaker 1P/2P/3P/4P Dual Power Manual Transfer Switch 6A~63A AC230/400V Interlocked MCB for Dual Source Power Conversion

Description 

Original CHNT NXB interlock dual power transfer circuit breaker, available poles:1P/2P/3P/4P, rated current range 6A/10A/16A/20A/25A/32A/40A/50A/63A, rated voltage AC230V(single phase)/AC400V(three phase).

Interlocking mechanical structure ensures only one circuit is switched ON at a time to avoid two power sources short-circuit; integrated overload, short-circuit & isolation protection, magnetic blow-out arc extinguishing, flame retardant housing, standard DIN rail installation. Widely used for household standby generator, UPS, residential dual mains power switching, small equipment dual-power distribution cabinet circuit conversion.
  • Safe Mechanical Interlock Structure:Exclusive interlocking mechanical linkage prevents both circuits closing simultaneously, effectively avoid short circuit caused by two different power source overlap connection.
  • Complete Protection Functions:Built-in overload, short-circuit and isolation protection same as standard NXB MCB, safeguard load equipment and power grid from abnormal overcurrent damage.
  • Full Spec Range:4 pole options + full current ratings from 6A~63A, cover single-phase 220V home and three-phase 380V industrial dual-power switching needs.
  • Flame Retardant & Stable Performance:High-quality flame retardant shell + magnetic blow-out arc extinguishing system, reliable arc breaking, long service life for frequent switching operation.
  • Wide Application Scenarios:Ideal for household municipal+generator/UPS backup power, villa dual mains supply, small pump & machine equipment dual-power automatic/manual switching control.
