Siemens SIRIUS 3TG10 Mini Contactor 3TG1010-0AC2, 3-pole, 24 V AC coil, 3 A AC-3, 1 NO auxiliary contact

The Siemens 3TG1010-0AC2 is a compact mini contactor from the SIRIUS 3TG10 series, engineered for reliable switching of small motors and resistive loads in industrial control panels. Its 24 V AC coil and 3 A AC-3 rating make it suitable for applications where space is limited but performance cannot be compromised.

Highlights

• 3 main poles with 1 NO auxiliary contact for control feedback
• Rated operational current of 3 A at AC-3 (400 V) for motor switching
• Wide coil frequency range of 45 to 450 Hz for flexible supply conditions
• DIN rail or screw mounting for easy installation
• High mechanical endurance of 30 million operating cycles

In daily use

This contactor is designed for switching three-phase motors up to 0.75 kW at 400 V AC-3, as well as resistive loads up to 6 A at AC-1. The screw terminals accept solid or stranded conductors, and the IP20 protection class on terminals ensures safe handling in enclosed panels. With an operating temperature range of -25 to +60 °C, it performs reliably in demanding environments.
