11.6 Surge Absorbers
A surge absorber absorbs surges or noises generated by a magnetic contactor (MC) or solenoid valve in the power
system to effectively protect electronic equipment in the panel from malfunctions or breakdown. Installed parallel to
a coil of an MC, solenoid valve, or L load, a surge absorber absorbs the surge voltage.
Applicable surge absorber models are the S2-A-O and S1-B-O. Figure 11.6-1 shows their external dimensions.
These products are available from Fuji Electric Technica Co., Ltd.
