Siemens 3RT2 Series Contactor, 24 V dc Coil, 4-Pole, 9 A, 4 kW, 2NO + 2NC, 400 V ac

Use this DC contactor from Siemens to switch an electrical circuit on or off. It’s compatible with main current, auxiliary and control circuits for versatility. Installation is straightforward, thanks to the unit's screw-type terminals, while compact dimensions of 57.5 (L) x 45 (W) x 73mm (H) save space. The contactor can be used to handle electrical loads, including lighting circuits, heaters and motors that are frequently switched on and off. Safely combine it with compatible products in the SIRIUS Innovation series, including load feeders, overload relays and motor starter protectors.

• Operating temperature range between -25°C and +60°C for safe industrial use
• 4kW power rating for demanding applications
• Stable and low-energy arrangement with a normal state configuration of 2NO/2NC
• 9A current rating to withstand medium-current systems

This contactor has a voltage rating of 400V DC, so it's suitable for motors and resistive loads.

A 3-pole conductor is used in a 3-phase electrical system. A 4-pole contactor has a 4th pole for a neutral supply. Choose this 4-pole contactor if you need to control non-inductive or slightly inductive loads.
