SIEMENS SIRIUS 3RV2 Motor Starter Protector, 0.18-0.25A, 3-Pole, Class 10, Screw Terminals, 3RV20110CA15

A compact motor starter protector that sets itself apart with a fixed magnetic short-circuit release at 3.3 A and a thermal overload range adjustable from 0.18 to 0.25 A. The SIRIUS 3RV2 series delivers dependable protection for small AC motors in industrial control panels, combining precise trip settings with a space-saving S00 footprint.

Highlights

• Adjustable thermal overload release: 0.18–0.25 A
• Fixed magnetic short-circuit release: 3.3 A
• High breaking capacity: 100 kA at 400 V AC
• 3-pole design with screw terminals for secure wiring
• Class 10 trip characteristic for normal motor starting
• Mounts on standard 35 mm DIN rail or via screw fixing
• IP20 finger-safe protection

In daily use

The 3RV20110CA15 sits directly at the motor branch, providing both overload and short-circuit protection without the need for separate fuses. Its thermal release reacts to sustained overcurrents, while the magnetic trip clears high-level faults instantly. The adjustment dial allows fine-tuning within the 0.18–0.25 A window, ensuring the motor is protected without nuisance tripping during normal inrush. Screw terminals accept solid or stranded conductors, and the clear switching state indication simplifies troubleshooting on the factory floor.
