Product Overview
Siemens SIRIUS 3RV2011-1JA10 is a size S00 3-pole manual motor starter protector designed for switching and branch circuit protection of three-phase induction motors. It integrates Class 10 bimetallic thermal overload protection adjustable from 7.0 to 10.0 A alongside a fixed 130 A instantaneous magnetic short-circuit release. The unit mounts directly onto standard 35 mm DIN rail and features a front-mounted rotary operating switch with visible tripped position indication.
Key Features
- Adjustable thermal overload dial from 7.0 to 10.0 A with Class 10 trip characteristic
- Instantaneous short-circuit magnetic trip set at 130 A
- Integrated top transverse auxiliary contact block with 2 normally open contacts
- Main screw clamp terminals accommodate 0.75 to 4 mm² (AWG 18 to 12) copper conductors
- Auxiliary terminals accept 0.5 to 2.5 mm² (AWG 20 to 14) wire
- Rated breaking capacity up to 100 kA at 400 V AC and 65 kA at 480Y/277 V
- Rated for 3-phase motor loads up to 5 HP at 460 V and 7-1/2 HP at 575 V
- Snap-on mounting for standard 35 mm DIN rail or screw panel installation
Applications
- Snaps onto control cabinet DIN rail to provide isolated manual disconnect and branch circuit overload protection for pumps or conveyors.
- Replaces worn manual motor protectors inside industrial control panels feeding three-phase machinery.
- Allows machinery builders and hobbyists to set up dedicated manual motor protection on shop machinery like milling spindles, table saws, or air compressors.
Frequently Asked Questions
Does this motor protector include auxiliary contacts for remote signaling?
Yes. A front transverse auxiliary block is installed, providing two normally open contacts wired to terminals 13-14 and 23-24 for run status signaling or PLC interlocking.
What wire sizes do the main terminal screws accept?
The main line and load terminals accept copper conductors ranging from 0.75 to 4 mm² (AWG 18 to 12) tightened to 0.8 to 1.2 Nm torque.
Can this unit be tested manually without an electrical fault?
Yes. A manual test slot located on the front face next to the adjustment dial allows mechanical verification of the trip mechanism.
What is the condition of this unit and what is included?
This is a used pull inspected visually without function testing, sold as an individual unit exactly as shown. No extra hardware, mounting screws, or manuals are included.
Solid German switchgear engineered to cut power before overcurrent turns your motor into scrap. Snap it onto the rail, set the dial, and put your panel back to work.
