Protective Wiring of Relay Contacts

Protective Wiring of Relay Contacts
Relay contacts are subject to electrical erosion. Especially with inductive and capac-
itive loads, the service life of the contacts will be reduced. For suppression of sparks
and arcing, components such as RC combinations, nonlinear resistors, series resistors
and diodes should be used.

Typical AC applications
with inductive load
1 Load
2 RC combination,

e.g., RIFA PMR 209
Typical RC combinations for
230 V AC:
capacitor 0.1 µF / 630 V,
resistor 100 Ω / 1 W
