Full product range: AC contactors, circuit breakers, capacitors, relays, current transformers, meters, switches and fuse cutouts from one China factory.

Low Voltage Electrical Products from a Ningbo Manufacturer

Ningbo Doto Electric supplies eleven product families for panel builders, distributors and OEMs: AC contactors (CJX2 and CJ19), thermal overload relays, miniature and moulded case circuit breakers, RCCBs, self-healing power capacitors, JKW5C compensation controllers, hour meters, counters, current transformers, limit switches, and high-voltage fuse cutouts, arresters and insulators.

Every product page lists rated current, coil voltage, breaking capacity and frame size, so a part can be matched to an existing installation without waiting for a datasheet. Products ship with CE and RoHS documentation, and OEM labelling, special coil voltages and custom packaging are available on volume orders.

Export packing is carton on pallet, FOB Ningbo or CIF to your port. Tell us the load type, motor power and control circuit voltage and we confirm the correct frame within one working day.
