Siemens SIRIUS 3RT Size S0, 3RT2 Contactor, 24 V ac Coil, 3-Pole, 25 A, 11 kW, 3NO, 400 V ac

Need to safely turn a high-power circuit on or off? Choose this contactor from Siemens. The three NO contacts are designed to open and close rapidly without arcing, making this product ideal for circuits that are switched frequently. Thanks to its operating voltage of 690V AC and its operating current of 40A, it's suitable for use in demanding applications. For ease of installation, the unit is designed for mounting on a DIN rail. It's typically used in applications such as lighting control systems and electric motors.

• Robust mechanical service life of 10 million switching cycles for long-lasting use
• Screw terminal method for secure connections
• Surge voltage resistance of 6kV to withstand sudden spikes in voltage
• Broad operating temperature range between -25°C and +60°C for use in demanding environments

Contactors and relays are both switching devices that use an electromagnetic coil to open and close a circuit. The main difference between the two is that contactors can handle higher loads than relays, so they're a better choice for use in high-power applications.
