Siemens 3RT2036-1AP60 Contactor

Siemens 3RT2036-1AP60 is a 3-pole power contactor designed for AC-3e motor control duties, capable of switching three-phase loads up to 51 A with a nominal 22 kW rating at 400 V. This compact unit, part of the 3RT2 family, uses screw terminals for the main circuit and a control/auxiliary circuit with spring-loaded terminals, and it ships in size S2. The coil is rated for 220 V AC at 50 Hz or 240 V AC at 60 Hz, enabling control from standard European control voltages; the 60 Hz variant is denoted by the -60 suffix. An auxiliary contact assembly provides 1 normally open and 1 normally closed contact for signaling or interlocking. Typical applications include starting and stopping three-phase motors, pumps, and fans in industrial control panels where a rugged, space-efficient motor-contactor is required and the coil voltage aligns with the available control supply.
