Siemens Sirius Control Relays- Series 3RH21- Features, Benefits and Description

Features

  • The 3RH21 control relays are suitable
    for industrial use according to
    DIN VDE 0106 Part 100 .
  • The Sirius 3RH21 control relays
    are based on the S00 frame size.
  • The contacts are NEMA A600/P600
    rated.
  • These units have high contact reliability
    at low voltages and currents for
    electronic circuits.

Benefits

  • 3RH21 control relays meet or
    exceed the requirements of NEMA,
    UL, CSA, IEC, VDE and other
    international standards.
  • The terminals are marked according to both
    North American and international standards.
  • Flexibilty to meet most applications.
    Product accepted in most countries
    around the world.
  • The relays share the same snap-on
    auxiliary contacts, timing modules, and
    contactor mountable timing relays that
    are used on the 3RT101 (S00) contactors.

Description

  • The Sirius 3RH21 control relays contact
    coil and coil of the release solenoid are
    both designed for uninterrupted duty.
  • The number of auxiliary contacts
    can be extended by means of front
    auxiliary switch blocks (up to 4 poles).
  • RC elements, varistor diodes or diode
    assemblies can be fitted to both coils
    from the front for damping opening
    surges in the coil.
