Siemens 3TF3110-0AF0 Contactor

Siemens 3TF3110-0AF0 is a 3-pole power contactor designed for motor control in industrial panels, rated for 12 A AC-3 and capable of switching up to 5 kW at 400 V. It uses Size 00 packaging and includes three main contacts plus a single auxiliary normally open contact (10E) for control wiring. The coil is compatible with 110 V AC (50 Hz) or 132 V AC (60 Hz) supplies, allowing operation from common control voltages. This Siemens Furnas Electric Co device is built for reliable switching and long life in standard AC-3 duty applications, and it is commonly integrated with Siemens overload relays and motor starters to form a complete motor-control circuit for small-to-medium sized motors in conveyors, pumps, and machine tools.
