Auxiliary Contact 1NO 10A
The SIEMENS 49AB10 is a side-mount auxiliary contactor rated for 10 A at 600 V AC. It provides a single normally open contact for control-circuit signalling in motor starter assemblies. The unit fits NEMA sizes 0 through 4, making it suitable for panel builders and maintenance engineers expanding starter functionality.
Upgrading starter control circuits
This contactor adds a feedback or interlock point to an existing starter without replacing the main power poles. The jump is worth it when a machine sequence requires an extra status signal or safety interlock and the original starter has no spare auxiliary blocks. It installs on the side of compatible NEMA contactors to extend control logic.
Sustained control-circuit duty
The contact is rated for continuous 10 A AC operation at the full 600 V rating, so it handles prolonged coil-drive or pilot-light loads without derating. Silver-alloy tips resist welding during repeated make-break cycles in automated sequences. Temperature rise stays within NEMA limits during extended closure, ensuring reliable signalling throughout long production shifts.

Questions about this item
Will the 49AB10 mount on the side of a NEMA size 3 contactor?
Yes, it is a side-mount auxiliary contact rated for NEMA sizes 0 through 4.
How do I install the 49AB10 and what step is often missed?
Snap it onto the side of the compatible contactor and verify the 1NO contact changes state when the main coil energises.
When should I replace the 49AB10 auxiliary contact?
Replace it if the single normally-open contact fails to close at 10 A or shows excessive wear after repeated 600 V AC switching cycles.
