What Do TS1, TS2, TS3, and TS4 Mean in ATS23, ATS46, and ATS48 Wiring Diagrams?

Resolution:
In the wiring diagrams of the Altistart ATS23, ATS46, and ATS48 soft starters, TS1, TS2, TS3, and TS4 refer to Transient Suppressors.

Transient suppressors are protective devices designed to reduce voltage spikes generated by relay and contactor coils. These voltage transients can damage electrical components, create electrical noise, or cause improper operation of control circuits.

By absorbing or limiting these transient voltages, TS devices help improve system reliability and protect sensitive equipment connected to the soft starter.
