Siemens SIRIUS 3RT2 Contactor, 230 V ac Coil, 3-Pole, 9 A, 4 kW, 3NO, 400 V ac

This robust contactor from Siemens' SIRIUS Innovation range provides a simple switching and protection solution for high-power loads in industrial environments. It works by making or breaking a power circuit, so you can use it as a motor starter. Thanks to thermoplastic housing, this is a durable and impact-resistant choice that won't break under pressure. With a wide operating temperature range of between -25°C and +60°C, you can rely on the unit to work effectively in harsh environments. It comes complete with a 10A fuse to prevent electric shock from short circuits.

• Power rating of 4kW makes it suitable for heavy-duty industrial applications
• 6kV surge rating to handle sudden voltage spikes and ensure electrical safety
• Standard snap-on DIN rail mounting saves on installation time
• IP20 (ingress protection) rating for resistance to dust and objects larger than 12mm in size

The main difference between a contactor and a relay is that a contactor is typically intended for 3-phase circuits while a relay is used with single-phase circuits.
