Podaj napięcie sterujące, rodzaj zasilania (prąd przemienny lub stały) oraz częstotliwość, jeśli dotyczy. Potwierdź kod cewki dostępnego dla wybranej serii kontaktorów.
Contact Arrangement
List the main poles and auxiliary NO/NC contacts separately. Identify which contacts are built in and which require an additional block.
Load and Switching Duty
Provide operating voltage, load current and switching duty. For motors, include starting, stopping, jogging or reversing requirements as applicable.
Brand and Model Markings
Review logo artwork alongside the model and coil identification. Keep the approved configuration readable for installation and repeat orders.
Opakowanie i instrukcje
Confirm unit boxes, carton labels and instruction language. Approve the packaging with the product sample before production.
Accessories and Mounting
Check dimensions and the proposed overload relay, auxiliary blocks or interlock against the selected series. Similar appearance does not establish compatibility.
Contactor Branding and Design Changes
Branding an existing contactor and changing its construction are different projects. Confirm the configuration first, then agree on the customization and approval work.
Brand an Existing AC Contactor
Confirm the switching duty, main-circuit ratings, coil code and contacts. Then review logo placement, identification, instructions and packaging. The approved sample should carry the same configuration as the order.
Review a Contactor Design Change
For changes to the construction, contacts or mounting, send the equipment requirements and drawings. Agree on feasibility, accessory fit, tests and tooling responsibilities before approving development samples.
From Contactor Selection to Production Approval
Keep the model, coil and contact arrangement consistent from technical review through sample approval and production.
List the load, switching duty, control supply and quantities.
Confirm contactor supply, accessories and branding work.

Approve the configuration, identification and packaging.
Record inspection checks, sample references and the delivery milestone.
Confirm quantities by coil code, packing and shipping terms.
Agree on tooling ownership and confidentiality before development.
AC Contactors and Motor Control Products
Choose AC contactors for the required switching duty, then review thermal relays and motor protection for the complete circuit. High-voltage DC contactors need their own DC load specification and should be selected separately.
Build a Contactor Range with Your Name on It
Send your motor or switching requirements, coil voltage, accessory list and quantities to CHAC Electric for review.
Uzyskaj swój plan OEM i ODMMatch the Contactor to the Load and Control Circuit
The main contacts switch the load; the coil operates the contactor. Specify both circuits separately, then confirm auxiliary contacts, mounting space and accessories for the equipment.
| Szczegóły techniczne | What to provide | Co potwierdzić |
|---|---|---|
| Load and duty | Load type, utilization category and switching requirements | Use the rating for the actual duty. An AC-1 current value should not be substituted for an AC-3 motor-duty rating. |
| Main circuit | Operating voltage, current and main pole arrangement | Check these together on the selected series. A motor-power value only applies under its stated voltage and duty conditions. |
| Zasilanie cewki | Control voltage, AC or DC, and frequency | Confirm the full coil code. Main-circuit voltage does not define the required coil voltage. |
| Auxiliary contacts | Required NO / NC arrangement and control function | List built-in contacts and additional auxiliary blocks separately. |
| Mounting and accessories | Dimensions, mounting arrangement, relay, interlock and clearance | Check the combination for the exact series. Accessories that look similar may not be compatible. |
| Order requirements | Quantity by model and coil, target market, marking and packaging | Use the same specification and artwork versions for the quote, sample and production order. |
Plan Contactor Supply for Your Equipment
Agree on the parts included, check the proposed model and keep a complete configuration reference for equipment builds and repeat orders.
List the Starter Parts You Need
As your AC contactor supplier, CHAC can review the selected series with the overload relays, auxiliary blocks or interlocks you need. Mark existing components that will remain in the equipment and identify the parts you want quoted. The proposed combination still needs model-specific compatibility and coordination checks; a contactor alone is not a complete protected motor starter.
Testing and Inspection for Your OEM/ODM Order
CHAC’s OEM/ODM customization quotation for industrial control products includes the costs of product compliance testing and reliability verification within the agreed project scope. Confirm the model, coil specification, load duty and any auxiliary contacts or accessories required. Agree on sample checks, testing scope and batch inspection records before approving the order. When comparing AC contactor manufacturers, use the same product specifications and testing scope, then confirm packaging and delivery requirements for your quantity.
Record Coil Codes for Repeat Contactor Orders
As a magnetic contactor supplier, CHAC can review repeat orders using the complete model and coil code for each equipment version. Send the previous order reference with the auxiliary contacts, accessories and quantities you need. Highlight changes to the control supply or parts list so they can be reviewed against the approved configuration; the main current rating alone does not identify a replacement.

Motor Control Product Procurement Questions
Resolve questions about switching duty, coil supply and starter components before approving a contactor order.
Should I use AC-1 or AC-3 to select a motor contactor?
Use the rating for the actual duty and voltage. AC-1 generally covers non-inductive or slightly inductive loads; AC-3 covers defined starting and stopping of squirrel-cage motors. An AC-1 current is not a substitute for the AC-3 rating. Send jogging, reversing or frequent-switching requirements to CHAC for a separate review.
Can a contactor with a DC coil switch an AC load?
Yes, when the specific contactor and coil combination supports the application. The control supply and switched load are separate circuits. Give CHAC the load ratings and the coil voltage, supply type and applicable frequency; AC and DC coils should not be assumed interchangeable.
Does NC refer to the main contacts or auxiliary contacts?
Confirm which contacts the description means. Record the main pole arrangement separately from the auxiliary NO/NC contacts and their control functions. An NC auxiliary contact does not make the main power contacts normally closed. Include both arrangements in the specification sent to CHAC.
Is motor power enough to select a contactor for jogging or reversing?
No. Include motor voltage and current, starting method, switching frequency and the actual jogging or reversing duty. CHAC also needs to review the utilization category, interlocks and protection arrangement. A power rating quoted for another duty or voltage does not establish suitability.
How do I check contactor, overload relay and circuit protection compatibility?
Send the exact contactor, relay and short-circuit protective device models, together with the project fault level. Check mounting, relay adjustment range and coordination evidence for that combination. Mechanical fit alone does not prove coordinated protection. Keep the approved models and drawings with the equipment specification.
Does lead time mean production completion, dispatch or arrival?
Ask which milestone the quoted date covers: production completion, inspection release, carrier handover, departure or arrival. Record it with the required approvals and named place or port. CHAC’s production commitment and an estimated transit time are different parts of the delivery schedule.
