Auxiliary Contact 1NO/1NC 10 A 600 V AC
The SIEMENS 49AB11 is a side-mount auxiliary contact block designed for industrial control circuits. It adds one normally open and one normally closed contact to compatible starters and contactors. The unit is rated for 10 A at 600 V AC and fits NEMA sizes 0 through 4.
Contact Configuration 1NO/1NC
The block provides exactly one normally open and one normally closed contact, giving two circuits in a single module. This configuration determines whether the part matches the control logic required by the application. Verify the schematic calls for a 1NO/1NC arrangement before ordering.
Thermals Noise and Power Draw
The device is a passive electromechanical switch with no active cooling, fan or power supply. It generates no audible noise during normal operation and draws no control power of its own. Heat rise is limited to the contact resistance at the rated 10 A load.

Questions about this item
What does the 10 A rating mean when the contact is installed in a starter circuit?
The contact can carry up to 10 amps of alternating current continuously without overheating in the mounted position.
What does the 600 V AC maximum voltage rating limit in practice?
It caps the highest alternating voltage the contact can switch safely; circuits above that level require a different component.
How does the side-mount design affect installation on a NEMA size 0 contactor?
The auxiliary block attaches to the side of the contactor, adding one normally open and one normally closed circuit without increasing the front footprint.
