Siemens 3RF2 Series Solid State Relay, 40 A Load Current, DIN Rail Mount, 600 V Load Voltage, 30V dc Control 3RF2440-1AC45

Siemens 3RF2440-1AC45 is a solid state relay from the 3RF2 series designed for industrial automation and control applications. It supports a maximum load current of 40 A and a load voltage of up to 600 V, making it suitable for medium-voltage systems. The relay is DIN rail mountable, allowing easy integration into control panels, and features screw terminals for secure connections.

This solid state relay operates with a control voltage range from 4 V dc to 30 V dc, energizing an optocoupler via an internal diode to switch the connected load efficiently. The zero cross switching function reduces electrical noise by switching at the zero crossing point of the AC signal, enhancing the reliability of connected equipment.

With dimensions measuring 100 mm in height, 45 mm in width, and 157.5 mm in length, the relay is compact for space-saving installation in industrial enclosures. It has an IP20 rating, which ensures finger protection and guards against solid objects larger than 12 mm, suitable for indoor industrial environments.

The device tolerates ambient temperatures from -25°C up to 60°C, making it resilient in harsh conditions. It is built with no mechanical moving parts, resulting in minimal wear and extended lifespan, perfect for motor controls, pumps, compressors, and other industrial machinery.

Reliable screw terminal connections ensure secure electrical contact even under vibration. Fast switching with 'On' delay of just 1 millisecond for efficient circuit control. Wide operating voltage range from 48 V to 600 V AC supports diverse applications.

IP20 rating provides protection against solid objects larger than 12 mm and finger safety. Compact dimensions and absence of moving parts result in long service life and reduced maintenance. Zero cross switching function minimizes electrical noise and wear.

Operates reliably in harsh industrial environments from -25°C to 60°C. Ideal for controlling motors, pumps, compressors, and other industrial loads. Manufactured in Germany, this Siemens relay complies with various international standards including EAC, VDE, UL, UKCA, RoHS, RCM, CSA, and CE, ensuring quality and safety.

Perfectly suited for industrial automation, electrical protection systems, manufacturing process control, HVAC, and water treatment systems, the 3RF2440-1AC45 relay offers robust performance and reliability.
