Siemens SIRIUS 3RV2011-1DA25 Motor Protection Circuit Breaker, 2.2-3.2 A, 3-Pole, Screw Terminal, Class 10

The Siemens 3RV2011-1DA25 motor protection circuit breaker stands out with its precise 2.2–3.2 A adjustable thermal overload range, making it ideal for protecting motors in that current band without nuisance tripping. Part of the SIRIUS 3RV2 series, it combines a compact S0 frame with robust short-circuit breaking capacity for reliable motor control.

Highlights

• Adjustable thermal overload release from 2.2 A to 3.2 A
• Magnetic short-circuit release fixed at 42 A for fast fault clearing
• 100 kA breaking capacity at 400 V AC for demanding applications
• DIN rail mounting and screw terminals for secure, easy installation

In daily use

This breaker mounts on a standard 35 mm DIN rail and connects via screw terminals, ensuring a vibration-resistant connection. The thermal release protects against sustained overloads, while the magnetic release trips instantly on short circuits. With an IP20 rating at the terminals, it is suitable for use in enclosed control panels.
