Surge Absorber
 Use surge absorbers to absorb lightning surge voltage and abnormal voltage from power supply
input lines.
 When selecting surge absorbers, take into account the varistor voltage, the surge immunity and
the energy tolerated dose.
 For 200-VAC systems, use surge absorbers with a varistor voltage of 620 V.
 The surge absorbers shown in the following table are recommended.

Note 1. Refer to the manufacturers' catalog for operating details.
Note 2. The surge immunity is for a standard impulse current of 8/20 μs. If pulses are wide, either
decrease the current or change to a larger-capacity surge absorber.
