Siemens SIRIUS 3RT Size S00, 3RT2 Contactor, 24 V dc Coil, 3-Pole, 12 A, 5.5 kW, 3NO, 400 V ac

Use this robust contactor from Siemens' SIRIUS Innovation range to control and protect industrial motors. It has three normally open (NO) contacts that are energised when a current passes through them. This triggers the safe starting of the motor. The electromechanical device also has an auxiliary contact that triggers a power cutoff when a surge current passes through it, protecting the attached motor from damage. With a surge voltage rating of 6kV, this contactor can handle sudden voltage spikes to enhance electrical safety. It has a tough thermoplastic housing that's durable and impact-resistant, so you can use it in harsh industrial environments. Units like this one are commonly found in compressors and air-conditioning systems.

• Power rating of 5.5kW makes it suitable for heavy-duty industrial applications
• Compact dimensions of 57.5 (length) x 45 (width) x 73mm (depth) for space efficiency in small enclosures
• Broad operating temperature range of -25°C to +60°C for use in demanding environments
• Mechanical service life of 30 million operations for reliable long-term performance

You can mount this contactor by simply snapping it onto a DIN rail. This is a quick and simple process that doesn't need any tools.
