COO (Country of Origin):: DE

Siemens Solid State Relay, 3NO Contact Configuration, 4 to 30V DC Control Voltage Range - SIRIUS Series - 3RF2450-1AC45

Speed through circuit control with this Siemens solid state relay. By opening and closing its circuit using semiconductors, it quickly responds to signals to keep up with intense switching demands. As the unit works without moving parts, it cuts the risk of disruption from mechanical wear for a long service life. Mounting the device into a cabinet takes seconds as it simply snaps onto a DIN rail. A large current rating of 50A means the component's a safe bet for handling heavy electrical loads, making it a versatile choice. You'll find SSRs like this managing power distribution systems and electric motor starters.

Features & Benefits

• Off-state leakage current of just 10mA to minimise wasted power
• Secure screw terminals to clamp down on disruption from movement
• Quick switch-on time of 1ms and 1/2 cycle, skipping through appliance preparation
• Handles surge currents up to 1150A, shrugging off damage from power faults

Can this product handle extreme temperatures?

Yes, this SSR works in operating temperatures between -25°C and +60°C to stand up to tough conditions.
