Do the TeSys SK contactors have coil suppression fitted as standard

No, the LC1SK** range of contactors do not come with coil suppression.

Varisters and Diodes are available, they clip into the side of the contacors.
Varisters
  • 24-48V ac/dc LA4SKE1E
  • 110-250V ac/dc LA4SKE1U
    Note:
    Protection provided by limiting the transient voltage to 2 Uc max.
    Maximum reduction of transient voltage peaks.
    Slight increase in drop-out time (1.1 to 1.5 times the normal time).
Diode
  • 24-250Vdc LA4SKC1U
    Note:
    No overvoltage or oscillating frequency. Slight increase in drop-out time (1.1 to 1.5 times the normal time).
