1. Start with your buyer constraints

Collect these details before you compare any control box:

• Motor rating of the pump or equipment, in HP or kW
• Supply voltage and frequency at the installation site
• Required cable length from the box to the connection point
• Certificate requirements in your target market or project
• Application type, for example a submersible well pump, irrigation or a pool or fountain
• Order quantity and packing, for distributors who plan shipments by carton

2. Specification checks against the published listing

Power fit. The listing covers motors from 0.3HP to 3HP (0.25-2.2KW). If your motor is outside this range, this listing does not cover it. Ask for confirmation before you go ahead.

Supply fit. The stated voltage is 220V/50Hz. If your site uses a different voltage or frequency, the published information does not show that the box is suitable. Get written confirmation from the supplier.

Cable length. The listed electric cable length is 0.75-1M. If your installation needs a longer lead, plan for it separately and confirm what the supplier can provide.

Certificates. The listing states UL/TUV/CE/CCC. Before you rely on them for a project or import, ask for the certificate documents that apply to the exact model you are ordering. Check that they meet the requirements of your market.

3. Application fit

The published application areas are:

• Well pumps (submersible water pumps)
• Electromechanical equipment
• Irrigation and agriculture
• Domestic and residential appliances
• Industrial use
• Swimming pools and fountains

If your use is not on this list, or it involves conditions the listing does not describe, ask for technical confirmation before you choose this box. Examples are a different motor type or an unusual installation environment.

4. Packing and order planning

The listing gives two packing quantities: 20PCS/CTN for the Submersible Water Pump Control Box and 12PCS/CTN for the Deep Well Pump Control Box. Distributors can use these figures to plan carton counts. Confirm which version you are ordering, because the two have different packing quantities.

5. A related listing to consider

The same catalog also has a Two-Phase Pump Control Box. Its published specifications are 1.1KW 1.5HP, a 4uF capacitor, 220V and 50HZ. The listing mentions plug styles: British standard plug, South Africa big plug and European standard. If you need a specific plug style, ask about this product and confirm which plug option comes with your order. The published information does not compare the two products directly, so choose based on your motor and supply details.

6. When this recommendation does not apply

The Single Phase Start Control Box listing does not cover your needs if any of these apply:

• Your motor is rated below 0.3HP or above 3HP
• Your supply is not 220V/50Hz
• You need documents, ratings or features that the listing does not state

This guide does not give prices, lead times, protection features or installation instructions, because the published materials do not include them. Request this information directly. Installation should follow the supplier's documentation and local electrical rules.

Next step

Send your motor rating, supply voltage and frequency, cable length, target market and quantity to JULU COUNTRY XIANGFAN SEALS FACTORY. Ask for confirmation of the model, the applicable certificate documents and the packing version before you place an order.
