Overview
To reduce noise potentials and for EMC considerations you may need to equip the inductive actuators with noise suppressors, e.g., anti-interference capacitors, at the point of interference.
Protective Circuit Types
The following table provides generic selection guidelines.
Type of Load |
Suppression Device |
Minimum Component Rating |
|
|---|---|---|---|
AC circuits |
50 Ω resistor in series with a 0.47 μfd nonpolarized capacitor across the load |
for 120 VAC-powered loads |
200 VAC |
for 220 VAC-powered loads |
400 VAC |

Consult relay and contactor manufacturers’ catalogs for commercial suppression devices matched to your particular products.
Example
