Siemens 3TH8293-0AM0 Three-Phase AC Contactor

Siemens 3TH8293-0AM0 is a three-phase AC contactor designed for industrial control panels, with a coil rated for 220–264 VAC. This Siemens device is used to switch three-phase loads in automation systems, such as motors and other powered equipment, when driven by standard control signals from PLCs or relays. Identifying the exact variant within the 3TH family, the 3TH8293-0AM0 carries Siemens' engineering for reliable operation in common control circuits. The 220–264 V AC coil rating enables operation from typical industrial control supplies, offering compatibility with widely used plant electrical environments. In a typical installation, energising the coil activates the contactor to control the power path to the connected three-phase load, while de-energising releases the circuit. This format is intended to simplify panel wiring by consolidating the switching function into a single robust module. When specifying this part for a project, verify it aligns with the application’s voltage class and control strategy, and consider any required accessory options from Siemens, such as auxiliary contacts or interlocks, to meet interconnection or safety needs. The description reflects the product’s stated identity as a Siemens three-phase contactor with a 220–264 VAC coil; for complete electrical ratings—current carrying capacity, mounting style, coil power, and life data—consult the official Siemens datasheet or Industry Mall listing for the exact variant 3TH8293-0AM0.
