3 Ph Contactor

The 3 ph contactor is specially designed for three-phase AC power circuits, serving as standard control components for medium and small three-phase motors, three-phase heating units, three-phase water pumps and fans. Favored by small overseas purchasers of foreign trade and complete cabinet manufacturers for its compact body and stable three-phase synchronous switching performance, our factory's 3 ph contactor covers medium and small current ranges from 9A to 95A with a maximum withstand voltage of 690V. Its symmetrical three-phase contact layout fundamentally eliminates motor burnout risks caused by single-phase premature disconnection, delivering a 40% improvement in three-phase synchronous breaking precision compared with ordinary general contactors, perfectly adapting to small electrical control boxes and built-in machine tool control cabinets with limited space.

This 3 ph contactor features an optimized reduced overall width that saves 30% cabinet installation space; buckle-type DIN rail mounting requires no additional tools to drastically boost on-site assembly efficiency. An integrated arc extinguishing structure is built in to minimize contact loss under frequent small-current startup working conditions. Coils adopt low-power enameled wire with temperature rise controlled within national standard limits during long-term operation, eliminating risks of overheating burnout. Expansion slots are reserved on the unit side for installation of one normally open and one normally closed auxiliary contacts to realize equipment operating signal feedback and interlock control of multiple equipment; a single 3 ph contactor can satisfy most control demands of medium and small three-phase equipment.

Application Fields

 

3 ph contactors are widely used for various medium and low-power three-phase industrial equipment. They control cooling pumps and spindle motors of lathes and grinders in the machine tool industry; small conveying and stirring equipment in food and packaging machinery; water pumps and exhaust fans for building supporting facilities; small environmental protection dust removal equipment and power distribution cabinets matched with photovoltaics; small mixers and lifting equipment on construction sites and other scenarios. The products comply with dual CE and CCC certifications, enabling direct export to Portuguese-speaking markets including Brazil and Portugal, Middle Eastern Arab countries and other regions while adapting to local three-phase power supply standards, making them high-volume best-selling single products for foreign trade agents.

The full range of 3 ph contactors supports one-stop OEM/ODM customized services. Customers may submit drawings or samples to propose personalized demands, and the R&D team completes customized sample development within 15-90 working days with cycles adjusted according to product complexity. Free samples are available for testing of standard models; sample fees apply for customized samples and will be fully refunded upon formal bulk order placement. The minimum order quantity is 10 pieces, and different current specification 3 ph contactors can be mixed within a single order to meet mixed batch procurement demands. Customizable items include special coil voltages, customer brand LOGO printing on housing, non-standard contact combinations and integrated dedicated supporting accessories.

Standardized protective packaging tailored for foreign trade export is adopted for 3 ph contactors. Each unit is independently sealed in an anti-static bag, high-density shockproof foam fills interiors to buffer impacts, and thickened export corrugated cartons form outer packaging. Fumigation-free wooden cases and pallet reinforcement can be provided free of charge for full-container bulk orders to eliminate moisture and extrusion damage during long-distance sea transportation. The factory supports multiple international trade terms including EXW, FOB and DDP. Standard in-stock products are delivered within 7-15 working days; reorder cycles for long-term customers are shortened by 30%-50% as molds and production processes are mature, enabling rapid replenishment without delaying agents' sales cycles.

Flexible settlement schemes adapt to domestic and overseas customers: standard in-stock 3 ph contactor orders adopt terms of 30% advance deposit with the remaining 70% balance settled before shipment; customized products require a 50% advance deposit with full payment of the remaining 50% balance prior to delivery. Settlement in major foreign currencies including US Dollars and Euros is supported, and a full set of export customs declaration documents can be provided. Tiered wholesale discounts are available for long-term cooperative and bulk purchasing agents, with greater unit price discounts corresponding to larger purchase volumes; specific discounts can be negotiated one-on-one through business communication.
