    DESCRIPTION APPLICATION EXAMPLES


    The MOM200A™ is designed to check and measure contact A. Measuring the resistance of a circuit breaker element
    resistances in high-voltage circuit breakers, disconnecting switches
    1. Connect the micro-ohmmeter to the circuit breaker.

    2. Set the current (100 A in this example).
    200 amperes or less are needed for measurement.
    3. Press the resistance pushbutton.
    Since the MOM200A weighs only about 14 kg (31 lbs), it is convenient
