Automatic Transfer Switches (ATS)
Automatic Transfer Switches transfer an approved load between defined electrical sources through a compatible switch and controller.
Product-type reference. The supplied make and configuration are confirmed in your quotation.
Information to include in your RFQ

Replacement and quotation checks
For a replacement, send the existing automatic transfer switches (ATS) reference and photographs of its markings, connections and mounting. Include the equipment drawing or datasheet where available. Identify which functions must remain unchanged and whether an alternative make is acceptable.

Define the source-transfer arrangement before ordering an ATS
An automatic transfer switch transfers a load between specified sources under its control arrangement. State the sources, load and switching sequence. Clarify whether you need a switching device, a controller or a complete engineered transfer assembly.
What to include in the quotation request
Selection input | Send with your RFQ | Why it matters |
|---|---|---|
Source and load | Identify the two sources, system voltage, poles and load current. | Confirm the neutral switching arrangement from the system design. |
Transfer sequence | State required operating and return conditions and delays. | Specify the approved transition and interlocking arrangement. |
Assembly scope | Separate switch, controller, enclosure and wiring requirements. | Do not assume that a standalone device is a complete transfer panel. |
Control interface | List generator start, indications and remote signals if needed. | Check each required control function against the proposed equipment. |

Questions about Automatic Transfer Switches (ATS)
What should I check before selecting automatic transfer switches (ATS)?
A changeover switch is not necessarily an automatic-transfer assembly. Preventing unintended source paralleling requires the specified interlocking and control design.
What information is needed to quote automatic transfer switches (ATS)?
Provide source voltages, phases and neutral arrangement; rated current, poles and fault duty; transfer sequence, delays and controller functions; interlocks, bypass needs and enclosure. Include the quantity, requested make or existing reference and delivery PIN code.
Is an ATS the same as an AMF panel?
An ATS handles source transfer under its specified arrangement. An AMF system can include generator starting and further control functions. State the required generator and transfer sequence so the quotation covers the correct system.
