3MT7012-0AA10-0AF2 3-Pole Power Contactors

Description for 3MT7012-0AA10-0AF2 3-Pole Power Contactors

The Siemens 3MT7012-0AA10-0AF2 is part of the SINOVA 3MT7 family of power contactors — compact, efficient and robust electrical switching devices intended for controlling three-phase motors or general power circuits in industrial and building automation applications. Its 3-pole design provides a dependable main circuit path, while an auxiliary contact enables control circuit integration. The contactor is suitable for standard operating conditions up to 400 V (AC-3 duty), and is often used for motor starting, switching of resistive or inductive loads, or as part of larger control / automation systems.

Scholarly-engineered by Siemens, this contactor meets high insulation and surge-resistance standards (insulation up to 1000 V, surge resistance 6 kV) and affords long mechanical life — rated for about 10 million switching cycles.

Compact and space-efficient (width 45 mm), it can be mounted on a standard DIN rail and accepts solid or stranded conductor cross-sections suitable for typical industrial wiring. Screw-type terminals for both main and auxiliary circuits ensure secure terminations. Together with nominal coil power and well-defined control voltage tolerance, it gives stable switching even under variable supply conditions
