When you need a star performance from your high-voltage relay, try this SIRIUS solid state contactor from Siemens. Rated for loads of up to 600V and 10.5A, it's a powerful choice for high-capacity circuits. You'll find devices like this used with electrical motors, lighting circuits and heating equipment. As it's a zero crossing type, you can be sure this relay won't switch power to the output circuit until the supply is at 0V. This prevents large in-rush currents at start-up, protecting sensitive electronic equipment from damage. With a lightning-fast turn-on time of just 1ms, this high-speed device responds rapidly when it's time to power up.

• DIN-rail mounting method makes installation easy
• Compact dimensions of 45 (L) x 104.5 (D) x 100mm (H) mean it's a good fit for tight spaces
• Wide operating temperature range between -25°C and +60°C for compatibility with extreme conditions

Thanks to its integrated cooling element, this innovative device protects itself against overheating, and since it's designed to work with high-power circuits, it also has a mighty 300A surge current resistance. A touch-proof IP20 rating means you don't have to worry about electric shocks if you accidentally brush your hand against the housing.
