Overview
The Siemens 3RV1011-1GA10 is a molded case motor protection circuit breaker (MPCB) part of the SIRIUS 3RV1 series. This Class 10 device provides automatic protection for three-phase AC motors against overload and short-circuit faults. With screw terminals and a manual on/off rotary handle for easy tripping, it is designed for demanding industrial environments where reliable motor protection is essential.
Key Features
- Motor Protection Class 10 with adjustable thermal release (4.5–6.3 A) and magnetic release (82 A)
- Compact Size S00 form factor for tight DIN rail installations
- Rated for 220–690 VAC, 50/60 Hz operation
- Screw terminals for secure, corrosion-resistant connections
- Manual on/off rotary dial control for intuitive load setting and emergency shutdown
- Standard switching capacity per IEC 60947-4-1
