Overview
The Siemens 3RV1011-0JA10 is a compact, current-limiting motor starter protector in the Sirius 3RV1 family. It combines thermal overload and instantaneous magnetic short-circuit protection in a single, space-efficient DIN-rail mount device. This manual motor protector is rated for motors up to 0.5 hp at rated currents and provides Class 10 overload trip characteristics (trips in 10 seconds or less at 1.4× rated current).
Key Features
- Adjustable thermal overload range: 0.7–1.0 A
- Magnetic instantaneous release: 13 A trip threshold for short-circuit protection
- ON/OFF rocker manual control mechanism
- Screw-type terminals for field wiring
- Standard 35 mm DIN-rail mounting for compact panel integration
- IP20 enclosure rating; suitable for indoor control cabinets
- Bimetallic heating elements for both AC and DC motor protection
- UL/CSA and IEC approved for global industrial applications
