SIEMENS Surge Suppressor for S00 Frame Contactors
This SIEMENS surge suppressor attaches directly to S00 frame contactors in the 3RH2 and 3RT2 series. It uses an integrated varistor to clamp transient over-voltages on the coil circuit. The accessory is supplied new and installs without additional wiring.
Suitable for 24-48V AC and 24-70V DC coil circuits
The unit protects contactor coils operating on 24-48V AC or 24-70V DC control voltage. It is not intended for circuits outside these ranges or for contactors with a different frame size. Applications requiring a different accessory type should select an alternative suppressor.
Clamping via varistor for S00 frame
The varistor element determines the clamping performance for the specified voltage windows. This single specification confirms whether the suppressor matches the coil voltage and frame size of the contactor being protected.

Questions about this item
Do I need a S00 frame 3RT2 or 3RH2 contactor to use this surge suppressor?
Yes, the suppressor is compatible with S00 frame contactors from the 3RT2 and 3RH2 series and mounts directly onto them.
Will this suppressor work with an older contactor that has a different frame size?
No, it is designed for S00 frame units only and will not fit contactors with other frame sizes.
How can I confirm the suppressor is active after installation?
When the contactor coil is energised within the 24-48V AC or 24-70V DC range, the internal varistor clamps voltage spikes, protecting the coil.
