| Installed Function |
When its control coil is energized, the contactor closes the three main poles to connect a motor or other load and changes the auxiliary contact for status, seal-in or interlocking logic. The coil voltage is order-code dependent and must be read from the installed device. |
| Main poles | 3 normally open |
| Built-in auxiliary contact | 1 normally open |
| AC-3 operational current | 32 A at 400 V |
| Motor rating | 15 kW at 400 V, AC-3 |
| AC-1 operational current | 55 A at 690 V |
| Rated insulation voltage | 1000 V IEC; 600 V UL/CSA |
| Main circuit voltage | Up to 690 V AC |
| Terminal technology | Screw terminals |
| IDENTITY | ROLE / DIFFERENCE | SELECTION POINT |
|---|---|---|
| A30-30-10 | 3 NO + 1 NO auxiliary | Requested contact arrangement; confirm coil code |
| A26 family | Lower AC-3 current class | Do not select only by enclosure size |
| A40 family | Higher AC-3 current class | Check overload relay and conductor range |
| AF contactor family | Electronic coil platform | Not a direct coil-for-coil substitution |
| 1 | Match the complete coil-voltage marking and frequency before ordering. |
| 2 | Confirm AC-3 motor duty or AC-1 resistive duty; the current ratings are not interchangeable. |
| 3 | Retain the auxiliary-contact arrangement required by the control circuit. |
| 4 | Check overload-relay coordination, short-circuit protection and conductor size. |
| 5 | Isolate all power and control sources before replacement. |

| 01 |
What must be matched before ordering A30-30-10?
Match the complete model text, all suffixes, electrical rating, revision, connectors, mounting and the host equipment identity.
|
| 02 |
Can A30-30-10 be selected by appearance alone?
No. Similar dimensions do not establish electrical or functional interchangeability. Use the installed label and circuit role.
|
| 03 |
What condition checks matter for A30-30-10?
Check terminals, insulation, heat discoloration, mechanical damage and any related cooling or protection hardware before installation.
|
| 04 |
What should be recorded before replacing A30-30-10?
Record wiring positions, jumpers, connector orientation, mounting hardware, companion components and operating settings.
|
| 05 |
What should be tested after installing A30-30-10?
Complete controlled energization, status and protection checks, then verify operation under the approved commissioning procedure.
