SIEMENS 3RH21401AK60 IEC control relay 4NO 110/120V AC 10A
IEC control relay with four normally-open contacts rated 10 A at 240 V AC and a 110/120 V AC coil for DIN-rail mounting
- Reliable AC switching with 110/120 V coil voltage
- Four normally open contacts simplify control circuit design
- 10 A AC rating handles standard industrial loads
- Screw terminals and DIN rail mounting speed up installation
- Low 5.7 VA coil consumption reduces panel power draw
IEC control relay 4NO 110/120V AC 10A
This SIEMENS IEC control relay provides four normally open contacts rated at 10 A for AC loads. It operates from a 110/120V AC coil drawing 5.7 VA. The unit is suited for machinery control panels and industrial automation tasks that require reliable switching at standard control voltages.
Screw terminal wiring DIN rail
Connections are made through screw terminals that accept standard ferrules or solid wire for secure termination. The relay mounts on DIN rail or directly on a panel surface using the integral mounting features. An IP20 rating protects against finger contact with live parts inside an enclosure. Frame size S00 keeps the footprint compact for dense panel layouts.
Compatible with Series 3RH21 control relays
The relay belongs to the 3RH21 series so it shares common accessories and replacement coils with other units in the range. This commonality simplifies spare-parts stocking and reduces downtime during maintenance. No additional software or configuration tools are required for basic installation and operation.

Questions about this item
What coil voltage does the 3RH21401AK60 need and what AC contact rating does that cap at 240 V?
The coil runs on 110/120 V AC and the AC-15 rating at 240 V is 10 A.
Which mounting styles and frame size does this relay use?
It fits DIN rail or surface mount and uses the S00 frame size.
How do you wire the coil and contacts, and what mistake should be avoided?
Use the screw terminals for both coil and contacts; do not exceed the 5.7 VA coil rating when sizing the control transformer.
