Installing CR-type surge absorbers
Provide AC-powered solenoids, contactors, relays, and induction motors with a CR-type
surge absorber.
For solenoids, contactors, and relays:
Note: A surge absorber must be installed as close to a coil as possible.
For induction motors:
Note: A surge absorber must be installed as close to a motor as possible.
Construction of a surge absorber
The recommended values of C and R are as follows:
• R = DC resistance of a coil (
Ω
)
•
Note: I = Steady-state current of a coil
