For effective motor control and protection, choose this contactor from the Siemens SIRIUS Innovation range. It works by switching the motor on or off and can offer short-circuit protection when used as a starter. It has an operating temperature range of -25°C to +60°C, so you can use it safely in demanding industrial environments. Thanks to minimal power loss of 3.8W, this is an energy-efficient choice for motor control. It has a mechanical service life of 10 million operating cycles, so you can rely on it for long-term performance in applications such as lifts and escalators.

• Screw-type terminals for quick and easy installation
• Contact voltage rating of 400V is suitable for use in low-voltage applications
• Ingress protection rating of IP20 indicates it's resistant dust and objects larger than 12mm in size, including fingers
• Rated surge voltage resistance of up to 6kV to withstand power spikes

With compact dimensions of 85mm (height), 45mm (width) and 107mm (depth), this contactor is a space-saving solution for smaller enclosures.
