DZ47-63 series MCB available in 1P,2P,3P,4P poles, AC230/400V, C-curve, rated current 1~63A, with overload and short-circuit protection, breaking capacity 6000A. 1P cuts live wire only for lighting branch; 2P cuts live and neutral for single-phase home incoming and high-power appliances; 3P cuts three live wires for 3-phase motor circuits; 4P cuts 3 live lines plus neutral for 3-phase 4-wire PV and factory main incoming. All models adopt DIN rail mounting, flame retardant housing.
DZ47-63 series Miniature Circuit Breaker (MCB) is DIN rail mounted modular low voltage protective switch. It works on AC 50Hz, rated voltage 230/400V power distribution circuits. It provides overload and short-circuit protection for residential, commercial and industrial power systems, and can also be used for infrequent manual switching of circuits. Available in 1P,2P,3P,4P poles, rated current from 1A to 63A, C-curve trip for lighting and general resistive loads.
1P: Breaks Live(L) only, Neutral remains connected. Single-phase branch, lighting circuit, compact distribution box.
2P: Breaks both Live(L) and Neutral(N). Single-phase main switch, air conditioner, water heater, home incoming circuit. Fully isolate L&N for higher safety.
3P: Breaks three Live lines L1/L2/L3. 3-phase 380V loads, motors, air compressors, three-phase power branch.
4P: Breaks 3 Live lines + Neutral N.3-phase 4-wire circuit, PV distribution, factory main incoming, full isolation of all poles.
