- 10 A AC rating at 240 V drives motor loads directly
- Screw terminals on DIN-rail frame simplify panel wiring
IEC Control Relay 10 A
The SIEMENS 3RH21311AK60 is an IEC control relay designed for switching auxiliary circuits in industrial control panels. It suits panel builders and maintenance engineers who need a compact relay with screw-terminal wiring on DIN rail or surface mounts.
Capacity and headroom
The relay carries 10 A at 24 V DC and 240 V AC, dropping to 3 A at 120 V AC and 0.3 A at 440 V DC. AC ratings reach 10 A at 240 V and 1 A at 690 V. Coil power is 5.7 VA at 110/120 V AC, and the IP20 housing limits use to protected enclosures.
Compatible 3RH21 series
The unit belongs to the 3RH21 series so it shares mounting footprint and terminal layout with other relays in that range. This allows direct replacement or side-by-side installation without redesigning the panel wiring or rail spacing.

Questions about this item
Will the 110/120 V AC coil on this 3RH21311AK60 contactor work with my existing 120 V control circuit?
Yes, the coil is rated for 110/120 V AC so it will operate directly from a standard 120 V control supply without any additional transformer or dropping resistor.
How can I verify the 3NO/1NC contacts are switching correctly after wiring the screw terminals?
Apply 110/120 V AC to the coil and measure continuity across each of the three normally-open and the one normally-closed contact; the NO paths should close and the NC path should open when the coil is energised.
Does the box include DIN-rail clips or must I order mounting hardware separately for the S00 frame?
The relay is designed for direct DIN-rail and surface mounting using the integral features of the S00 frame, so no separate clips are required for standard installation.
