3RT1070-6AP30

The Siemens SIRIUS 3RT10 series S12 large-frame power contactor has a coil voltage rating of 220-240V AC/DC. It belongs to the same voltage category as the 6AP36 contactor and inherits the S12 frame design. It comes standard with 2NO+2NC auxiliary contacts and is suitable for use with large motor control panels and high-power power distribution systems. It is of stable original quality.

3RT1066-6NP36

The Siemens SIRIUS 3RT10 series S10 large-base power contactor has a main circuit rated AC-3 of 300A and 160kW (400V). It adopts an electronic operating mechanism, supplies 200-277V AC/DC power and has a 24V DC PLC interface. It comes standard with 2NO+2NC auxiliary contacts and is suitable for PLC automation control systems.

3RT1066-6NB36

The Siemens SIRIUS 3RT10 series S10 large frame contactor, AC-3 rated 300A, 160kW (400V), adopts the same electronic operating mechanism and has a PLC interface, but the power supply is about 20-33V (approximately 24V) AC/DC, which is a different voltage classification from the 200-277V of the 6NP36.
