When you're after an efficient way to manage electric motors, take charge using this contactor from Siemens. It amps up on-the-job safety by switching a circuit's power supply on and off using ultra-fast spring-loaded contacts. As it has a 25A current rating, you can connect this versatile contactor to lighting and heating systems, as well as vehicles and other high-current devices. The unit stands up to industrial load demands thanks to a contact voltage rating of 400V AC and a power rating of 11kW. An opening delay between 4 and 16ms means you can be sure it acts quickly when every second counts.

• Broad operating temperature range between -25°C and +60°C means it performs under harsh conditions
• Mechanical service life of up to 10 million switching cycles indicates longevity
• Front and terminals are IP20-rated, so are protected against objects bigger than 12mm
• Screw terminals clamp down on wires to make installation simple
• Short-circuit protection keeps your equipment safe during power faults

The unit comes with three poles, which means you can manage multiple circuits at once.
