Siemens Solid State Relay, 3 Poles, 48 to 600V AC Operating Voltage Range - 3RF2420-1AC45


Control the flow of current to your devices using this solid state relay from Siemens. As it features zero-cross switching, it helps to reduce noise by turning on when the load current is near 0V. You can snap this unit onto a DIN rail and screw it firmly in place, so installation is quick without the need for specialised tools. Screw terminals help to ensure secure and vibration-proof electrical connections. The relay has built-in short circuit protection to minimise the risk of electrical damage caused by faults. You'll find an SSR like this one used in heating and lighting applications.

Features & Benefits


• Wide operating voltage range between 48 and 600V AC for wide compatibility
• IP20 rating means it's finger-safe and protected against objects larger than 12mm
• Broad operating temperature range between -25°C and +60°C for use in demanding environments

What's the advantage of a solid-state relay?


Unlike electromechanical relays, SSRs have no moving parts. This means there's a very low risk of wear, which prolongs the life of the unit. SSRs also switch on and off much faster than electromechanical relays, so they're a good choice for use in applications where you need sensitive switching.
