Surge capacitors stay on all the time, they are sized to limit current at 60Hz but a spike is a high-frequency event so ends up flowing right through the capacitor. They''re used to protect windings where a fast rise-time surge might not trigger arrestors but could still cause a failure between the winding turns.
