Product Overview
Siemens SIRIUS 3RV2011-1CA10 size S00 manual motor starter protector provides branch circuit and thermal overload protection for small three-phase motors. Dial adjustment allows precise setting between 1.8 and 2.5 amps full load current, matched with a fixed 33-amp magnetic trip for instantaneous short-circuit interruption. This unit includes a front-mounted transverse auxiliary contact block featuring two normally open (NO) contacts for remote run indication or control interlocks.
Key Features
- Adjustable thermal overload dial range: 1.8 A to 2.5 A (Class 10 trip curve)
- Instantaneous magnetic short-circuit release rated at 33 A
- Frame size S00 with standard 35 mm DIN rail or screw panel mounting
- Rated operational voltage up to 690 V AC (50/60 Hz)
- Interrupting capacity: 100 kA at 400 V AC; 10 kA at 690 V AC
- UL and CSA listed as manual self-protected combination motor controller (600 V, 2.5 FLA max)
- Screw clamp terminals accepting stranded or solid wire, rated 0.8 to 1.2 Nm
- Includes top transverse auxiliary switch block with 2 NO contacts (terminals 13-14 and 23-24)
Applications
- Protects fractional-horsepower 3-phase pumps, blowers, and conveyor drives in industrial control panels.
- Acts as a manual motor disconnect and branch protection switchboard component on machinery rebuilds.
- Bench power supply protection and DIY machine tool spindle motor control for maker workshops.
Frequently Asked Questions
Does this motor protector snap onto standard 35 mm DIN rail?
Yes. The rear molding features a spring-loaded latch that secures directly to standard 35 mm symmetrical DIN rail (hat rail) or allows screw panel mounting via base tabs.
Are the auxiliary contacts integrated or detachable?
The unit includes a front-mounted transverse auxiliary contact block wired to terminals 13-14 and 23-24 (2 NO). It can remain in place for remote signal interlocking or be disconnected if auxiliary signaling is unneeded.
What do I need to connect or run this motor controller?
It installs directly in-line between your main three-phase supply and the motor terminals using screw clamp connections torqued between 0.8 and 1.2 Nm. No external heater packs or separate overload relays are required.
Built for the panel builder who knows true motor protection means dialing in the exact running amps instead of trusting a sloppy fuse. Snap it to the rail, terminate your three phases, and put the machine back on the line.
