Siemens SIRIUS 3RU2 Thermal Overload Relay 1NO + 1NC, 11 → 16 A F.L.C, 16 A Contact Rating, 7.5 kW, 3P, SIRIUS

Stem the tide of voltage surges with this overload relay from Siemens. You can count on it to protect and extend the lifespan of your equipment and limit service interruptions. It disconnects power to a connected circuit when it picks up a current spike outside its rated 11 to 16A FLC rating. As a Class 10 relay, it trips in 10 seconds or less, making it a fast responder to electric faults. The unit handles temperature extremes between -40°C and +70°C without breaking a sweat, so you can confidently use it in demanding locations. Overload relays such as this one are important components for the motors driving your medical, industrial and marine-type machinery.

• Screw terminals secure conductors reliably to prevent accidental disconnections
• 7.5kW power rating makes it an energy-friendly unit
• 3-pole device covers multiple circuits at once

Yes, a built-in selector switch allows you to choose between automatic or manual resetting. If you go with the first option, the unit will get the circuit running again when the fault is eliminated.

Yes, its casing carries an IP20 rating, which means it's touch-proof.
