Star-delta starter with a delay setting of 3-30 sec, suitable for use in automation systems for starting three-phase asynchronous motors.

Provides contacts for the direct actuation of the star relay, the delta relay, and the main relay. Offers contacts for the direct connection of start and stop buttons as well as the automatic operation switch, thus replacing the entire electrical automation for starting.

Functions as a normal delay timer (3-30 sec) for switching from star to delta after command from either the buttons or the automatic operation switch. Also introduces a time of 20-300ms (Transition time) between the operation of the star and the delta.

Features:

• Output relay: Three independent, single-pole contacts 10A / 250VAC cat. AC1.
• LED indicators: Power On and Relay On.
• Varistor protection against surges and lightning.
• Connection base: Type screw terminal, 8p.
• Operating temperature: -20º to +50º C.
• Delay time: 3 - 30 sec.
• Dimensions: 42x89x100mm.
