    Product Details

    Siemens Auxiliary Contact, 6A Operating Current, 17g Weight - SIRIUS Classic Series - 3RH1921-1CA01


    Looking for a trusty sidekick for your motor control units? This auxiliary contact from Siemens fits the bill. It's designed to switch alongside your contactors and relays, so you can use it to control vital peripheral functions like signal operating and malfunction states. The auxiliary contact has screw terminals, so connecting wires is a cinch, saving installation time and effort. Its thermoplastic housing provides not just impact resistance, but also reliable insulation to prevent you from receiving shocking surprises during operation. It's an essential piece of kit that you'll find in common industrial applications, including conveyor systems and compressors.

    Features & Benefits


    • High surge voltage resistance rating of 6kV to handle sudden voltage spikes without suffering damage
    • Wide operating temperature range between -25°C and +60°C for use in demanding conditions
    • Current rating of 6A makes it suitable for medium-current-consuming applications

    Is this auxiliary contact finger-safe?


    Yes, this unit has an IP20 rating, which means that it's touch-proof and protected from objects larger than 12mm in size, including wires and tools. This prevents accidental contact with live parts during operation for improved safety.
