Starters with long start times For applications when a long run-up time is required, the type Y91A timer is used with a delay of 10-60 seconds, and the overload is mounted on the Delta contactor. Add ‘L’ to the ordering code eg: K2-YL52SMI. Finger touch protection Types K2-Y15 to K2-Y52 incorporate finger touch protection as standard. For K2-Y80 to K2-Y200 it is necessary to fit an additional cover, refer to accessory section.
