    Extremely reliable contacts at low voltages and low currents

    Overview
    The 3RH2 intermediate relay is designed in accordance with IEC 60947 and EN 60947.
    The 3RH2 intermediate relay is available with screw, spring or ring terminals and can be operated with AC or DC.
    The 3RH2 intermediate relay is suitable for any climatic conditions and has a "finger touch protection" function in accordance with EN 50274.


    Contact reliability
    Under the condition of low voltage and low current, the contact has extremely high reliability and meets the use requirements of solid-state circuits. The minimum switch-on current is 1mA under 17V voltage.

    Surge suppression
    Resistive-capacitive absorption (RC), varistors, diodes, and diode combinations (diode and zener diode combinations) can be plugged into the front panel of the intermediate relay to suppress surges when operating the coil.

    Note:
    Using surge suppressor to suppress coil overvoltage will cause contactor normally open contact NO opening delay and normally closed contact NC closing delay (suppression diode will increase delay by 6 to 10 times, diode combination will increase delay by 2 to 6 times, and varistor will increase delay by 2 to 5ms).
