It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, in any position, and occupies 45 mm of panel width with a 97 mm depth — a compact footprint that leaves room for contactors and overload relays on the same rail. The main circuit connection uses spring-loaded terminals accepting 2x (0.5 to 4 mm²) solid or stranded wire, which speeds panel wiring and maintains consistent clamping force over time compared to screw terminals. ## Breaking Capacity and Short-Circuit Coordination Rated breaking capacity reaches 100 kA at 240 V, 400 V, and 500 V AC, dropping to 10 kA at 690 V AC. This 100 kA figure at common distribution voltages (400 V) means the breaker can safely interrupt high-fault-current scenarios without upstream fuses or a larger frame — a key advantage in high-capacity MCCs or transformer-fed panels where available fault current exceeds 50 kA. For backup fuse coordination, the unit is rated for gL/gG fuses: 25 A at 400 V and 500 V, 20 A at 690 V. This lets the designer size the upstream fuse to match the breaker's let-through energy without over-fusing the branch. ## Integration and Mounting Notes Clearance requirements: 50 mm upwards and downwards, 30 mm to the side, 0 mm forwards and backwards — so the breaker can sit flush against a panel backplate or enclosure wall without additional standoffs. Ambient operating range is -20 to +60 °C; storage and transport range extends to -50 to +80 °C.","metaTitle":"Siemens 3RV2011-1BA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2011-1BA20 SIRIUS motor protection circuit breaker, Trip Class 10, 100 kA breaking capacity at 400 V AC.

The 3RV1011-0GA10 is a narrower (45 mm) variant with lower breaking capacity. Neither is a drop-in replacement without verifying the short-circuit rating and terminal type against your BOM."},{"question":"Where can I buy the 3RV2011-1BA20 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent industrial-automation distribution. Availability and current pricing are confirmed at quote time.

However, the 3RV2011-1BA20 uses spring-loaded terminals while the 3RV1011-0GA10 uses screw terminals — verify that your wiring lugs and ferrule sizes (0.5 to 4 mm²) are compatible before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV2011-1BA20","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RV2011-1BA20 when reusing this data.
