Siemens 3RT1023-1AK60 Three Phase AC Contactor

Siemens 3RT1023-1AK60 is a three-pole Sirius AC-3 contactor with three normally open (NO) main contacts and no normally closed contacts, designed to switch three-phase motors. It supports 9 A at 400 V (AC-3) and 4 kW at 400 V, with a size S0, screw-terminal main circuit. The unit is front IP20 protected, uses screw terminals, and is rated for operation from -25 to +60 C and installation up to 2,000 m above sea level. Coil voltage options are 110 VAC (50/60 Hz) or 120 VAC (50/60 Hz), and the contactor delivers long mechanical life—about 10,000,000 cycles for the base unit (5,000,000 cycles with compatible auxiliary or electronics-compatible auxiliary block).
