Product Positioning

The 3RT1064-6NB36 is a Siemens SIRIUS S10 large power contactor. It replaces the traditional electromagnetic coil with an electronic operating mechanism, allowing direct drive from a PLC 24V DC output signal. This eliminates the need for relays and surge protection components, simplifying control panel wiring. Its three-pole design with a 225A AC-3 rated current makes it suitable for direct starting applications of large motors. Kenxin Motors is an authorized Siemens distributor, providing genuine Siemens products and technical consultation.
