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.
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.
