definite purpose contactor quotation alignment

Requirements, factory inquiries and quote comparison for a definite purpose contactor, written so several plants answer the same lines.

Coordination stages for a definite purpose contactor request

The shortest request a supplier can still quote from names coil voltage with AC or DC, main-contact amperes for the stated duty, pole count, quantity and destination. Horsepower without voltage and phase is not accepted as a substitute for those lines. Items driven by quantity—carton count, spare coils, extra auxiliary decks—are listed separately from one-off accessories such as a mechanical interlock kit that belongs to one reversing pair.

1 Requirement

We restate the electrical duty in writing: coil, contacts, poles and load. You approve the restated sheet before it is sent.

2 Supplier search

We identify factories that publish that construction. Search is not a claim that those plants already hold stock for your rating.

3 Quote comparison

We line up offers on one basis: same coil, same poles, same accessories in or out. Unstated test conditions stay unmatched.

4 Order follow-up

We track the checks you agreed in writing. Shipment timing exists only after the chosen supplier confirms quantity.

Contact ampere rating and pole count have to be fixed before the request is sent. A 40 A resistive line and a motor horsepower line are different facts; they are not averaged. If you only know the compressor nameplate, send rated load amperes, locked-rotor amperes, voltage and the control voltage at the unit. We will ask which number the factory should quote against. Soft starters and direct-on-line starters are out of this page's scope and need a different brief.

Open the inquiry options if the construction is still unnamed, or the application page if the duty comes from an air-conditioning unit. Unclear lines go to contact.

Fix coil voltage, contact amperes, poles, quantity and destination. Optional budget and supplier preference can ride in the same box. They do not replace the rating lines.
