Product Overview
Engineered for small three-phase motor circuits, Siemens SIRIUS 3RV2011-0GA10 delivers Size S00 three-pole motor starter protection and manual disconnect control. Built with both thermal bimetallic overload release and magnetic short-circuit protection, this unit safeguards connected loads against overload damage, phase failure, and downstream fault currents. The front-mounted rotary operator provides positive ON/OFF manual switching, clear trip status indication, and lockout capability in the OFF position. Designed for standard 35 mm DIN rail mounting or direct panel screw installation, it serves as a manual motor controller or standalone motor branch circuit protector.
Key Features
- Adjustable thermal overload protection spanning 0.45 A to 0.63 A full load current.
- Instantaneous magnetic short-circuit trip release rated at 8.2 A.
- CLASS 10 overload trip characteristic for standard induction motor start cycles.
- Rated operational voltage up to 690 V AC (50/60 Hz).
- High breaking capacity rated at 100 kA at 400 V AC and 100 kA at 690 V AC (Icu / Ics).
- UL and CSA certified as a Manual Self-Protected Combination Motor Controller.
- Heavy-duty screw clamp terminals accepting 0.75 to 4 mm² (AWG 18 to 12) solid or stranded wire.
- Compact Size S00 modular frame designed for standard 35 mm DIN rail or surface mounting.
Applications
- Mounts inside an industrial control cabinet to protect fractional-horsepower pumps, agitators, or blower motors.
- Replaces a worn motor circuit breaker in factory automation panels or packaging machinery.
- Safeguards custom workshop machinery, conveyor drives, and CNC auxiliary spindle motors.
- Provides dedicated disconnect and overload defense for small three-phase machinery in maintenance shops.
Frequently Asked Questions
How is the trip current adjusted on this starter protector?
The front dial features an adjustable pointer calibrated from 0.45 A to 0.63 A. Using a standard screwdriver, set the dial indicator directly to the full-load amp (FLA) rating shown on your motor nameplate.
What wire size and tightening torque are required for the main terminals?
The screw terminals accommodate conductor sizes from 0.75 to 4 mm² (AWG 18 to 12). Recommended tightening torque is 0.8 to 1.2 N·m (7 to 10.3 lb·in) using a Pozidriv PZ2 screwdriver.
Can this breaker be mounted in any orientation?
The 3RV2011-0GA10 mounts directly onto standard 35 mm DIN rails (EN 60715) or mounts with screws via panel adapter holes. Standard vertical installation is typical, though horizontal mounting on DIN rail is also supported.
What am I receiving with this used unit, and what condition risk is involved?
This unit is surplus pulled from decommissioned industrial equipment. Physical inspection confirms intact housing, functional rotary handle mechanics, and clean terminal screws. Function testing was not performed, so the buyer assumes operational testing upon receipt. The listing includes only the single Siemens 3RV2011-0GA10 motor starter protector shown in the photographs; no manual, mounting screws, or additional hardware are included.
Dialing in fractional-amp motor protection is all about keeping small three-phase machinery running without nuisance trips or burnt windings. Snap it onto the rail, dial your motor's full-load current, and put the machine back on the clock.
