Product Description
Siemens 3RF2450-1AC45 Solid State Relay from the 3RF2 Series handles a maximum load current of 50 amps and a maximum load voltage of 600 volts, controlled via 4 to 30 volts DC. This robust relay is engineered for DIN rail mounting, enabling fast, tool-free installation in electrical cabinets.
The solid state relay operates using thyristor output technology with zero cross switching to reduce electrical interference and extend appliance life. Its swift switch-on time of 1 millisecond and half cycle response makes it suitable for applications demanding rapid switching.
The device supports an operating temperature range from -25°C to 60°C, making it reliable for industrial, manufacturing, and automation environments requiring thermal endurance. The low off-state leakage current of just 10mA ensures energy efficiency during standby.
Secure screw terminals prevent connection disruption from vibrations or movement. The relay's compact size (180 mm height, 157.5 mm length, 45 mm width) enables integration into space-constrained control panels. It is certified to standards including EAC, CSA, CE, VDE, UL, UKCA, RoHS, and RCM.
Commonly used in power distribution systems and electric motor starters, this Siemens solid state relay ensures long operational life by eliminating mechanical wear through semiconductor switching.
Designed for DIN rail mounting with fast snap-in installation. Zero cross switching reduces voltage and current surges. Handles peak surge currents up to 1150A for durability. Robust operation in temperatures from -25°C to 60°C.
Compact dimensions suitable for control panels. Minimal off-state leakage current improves energy efficiency. Secure screw terminals maintain reliable electrical connections. Certified by multiple international safety and quality standards.
This product, made in Germany by Siemens, is ideal for industrial automation, electrical cabinets, power distribution, and motor control applications. EnvMart offers this reliable Solid State Relay for enhanced electrical system performance and longevity.
