SIEMENS 49AB22 Auxiliary Contact

The SIEMENS 49AB22 is a side-mount auxiliary contact block rated for 10 A at 600 V AC. It provides four contacts in a 2NO/2NC configuration for industrial control circuits. The block fits NEMA size 0 through 4 starters and contactors. Electricians and panel builders use it to add signalling or interlock functions to motor control centres.

Upgrading contact capacity or contact count

Replace a worn contact block or add extra poles when the existing starter has no free positions. The jump is worth it when a circuit needs both normally open and normally closed signals from the same device. It also suits panels being expanded to meet new safety or monitoring requirements without changing the base contactor.

Check mounting side and NEMA size before ordering

Verify that the target starter or contactor accepts side-mount blocks and falls within NEMA size 0 to 4. Confirm the control voltage and current do not exceed 10 A at 600 V AC. Ensure the enclosure has enough space for the additional block and that wiring routes remain compliant with local codes.

Questions about this item

Does the 49AB22 auxiliary contact fit NEMA size 0 starters?

Yes, the contact is rated for NEMA sizes 0, 00, 1, 2, 3 and 4, so it mounts directly on a size 0 starter.

How do I mount the 49AB22 on the side of a contactor?

Align the side-mount brackets with the contactor slots, slide the unit in until the latch clicks, then secure the captive screws — skipping the latch click is the common error.

When should the 49AB22 auxiliary contact be replaced?

Replace the block if any of the four contacts show pitting, overheating discoloration, or if the 10 A / 600 V AC rating is exceeded during routine inspection.
