Siemens 3RT2 Series Contactor, 24/34V DC Coil Voltage, 20A Contact Current - 3RT2017-1XB42-0LA2

This contactor is an electromagnetic switching device designed for controlling three-phase loads in industrial and rail traction environments. It operates with a DC Coil and is suited to switch AC circuits under defined utilisation categories, providing a Compact DIN-rail mount solution for control panels and traction equipment.

Features and Benefits:

• 24/34V DC Coil delivers controlled actuation for DC-operated systems
• Three poles with 400V rating enable three-phase switching for motors
• 20A contact capacity supports moderate current AC loads
• 12A operational current for defined continuous use cases
• Single NC auxiliary contact offers interlock or signalling capability
• Screw terminals ensure secure electrical connections under vibration

Applications

• Suitable for motor starters in AC-3 switching
• Used for traction control modules in railway equipment
• Ideal for remote switching in industrial control cabinets
• Can be used for pipe S-type mirror contact arrangements in panels

What ambient temperatures can it tolerate during operation?

It is specified to operate between -40°C and 70°C, accommodating cold starts and elevated enclosure temperatures.

How is the unit mounted within control gear?

The product is designed for DIN-rail mounting, enabling Rapid installation and alignment in standard switchgear racks.

What approvals support its use in rail applications?

It carries approvals relevant to railway service including PRS and RMRS, permitting deployment in rolling stock and related systems.

How does the Terminal type affect maintenance?

Screw terminals allow torque-controlled connections and straightforward replacement or retightening during scheduled service.
