Siemens SIRIUS 3RT2 Contactor, 110 V ac Coil, 3-Pole, 9 A, 4 kW, 3NO, 400 V ac

Make or break an electric circuit in your device with this contactor from Siemens. When its coil receives electrical energy, it rapidly opens and closes the internal contacts to send current to attached devices. A mechanical service life of 30,000,000 cycles means it can easily keep up with demanding operations that call for constant switching. To step up the unit's performance, you can add an auxiliary switch to monitor its contact state. Getting set up is simple – just snap the contactor onto a DIN rail and use it to run heavy-duty equipment such as HVAC systems.

• Low power loss of 0.7W for energy-efficiency
• Safe to use in challenging environments, thanks to an operating temperature range between -25°C and +60°C
• Surge voltage resistance of 6kV to withstand excess current supply

A short contact opening delay between 3.5 and 14ms and a closing delay between 9 and 35ms means the contactor delivers reliably quick signals.
