SIEMENS 3RH21221AB00 contactor 2NO/2NC 24V AC 10 A
IEC control relay with 2NO/2NC contacts, 24V AC coil and 10 A AC rating
- IEC-standard relay fits standard DIN-rail panels
- 10 A AC rating handles motor-start currents
- 24 V AC coil suits common control voltages
- 2NO/2NC contacts give flexible circuit logic
- Screw terminals provide secure tool-less wiring
IEC control relay 2NO/2NC 24V AC
This SIEMENS IEC control relay provides four contacts in a 2NO/2NC arrangement with a 10 A current rating and a 24V AC coil. It is suited for panel builders and maintenance engineers who need a compact relay for machine control circuits.
DIN rail or surface mount with screw terminals
The unit fits a standard DIN rail or can be surface mounted using screw terminals for secure wiring. Its S00 frame size keeps the footprint small, freeing panel space for other components in dense control cabinets.
IP20 rating and 5.7 VA coil consumption
The IP20 enclosure protects against finger contact while the 5.7 VA coil draw keeps control-transformer loading low. These characteristics simplify integration into existing 24V AC control systems without extra accessories.

Questions about this item
What coil power draw should I budget for when this relay runs continuously?
The coil consumes 5.7 VA at 24 V AC, so the supply must deliver that apparent power continuously.
How much heat or noise does the relay produce during all-day operation?
The coil draws 5.7 VA and the enclosure is IP20, so only modest warmth is generated and there is no fan or audible switching noise.
What wiring and mounting hardware must I already have to install this relay?
You need screw-terminal wiring tools and either a DIN rail or a flat surface with mounting screws for the S00 frame.
