Description
The Siemens 3RH1921-1HA31 auxiliary switch block is a phased-out product from the SIRIUS line, designed for integration with motor contactors sized S0 through S12. Featuring a 4-pole configuration (3 normally open and 1 normally closed contacts), this component adheres to EN 50012 standards and employs screw terminal connections for reliable coupling in industrial applications. Its compact form factor measures at 51 x 45 x 64 mm, with a net weight of only 0.066 kg.
Constructed under product class C specifications, it is tailored for specific use cases where reuse or returnability are restricted. Environmental compliance includes adherence to RoHS substance restrictions since July 2006 and WEEE take-back obligations under the EU Directive on waste electrical equipment disposal.
End-of-life classification denotes its replacement by models in the updated SIRIUS series, specifically the successor model category such as the Spring-type connection system version—3RH1921-2HA31—for enhanced operability within similar motor control setups. For purchasers focused on sustainability and regulatory compatibility during procurement planning, detailed documentation including REACH duty-to-inform criteria is available through Siemens product datasheets upon request.
This Czech Republic-origin auxiliary module carries commodity code "85365080" and integrates seamlessly into heavy-duty electrical systems requiring standardized performance reliability across global distribution channels.
