Siemens 3RV6011-1GA15 — SIRIUS Motor Protection Circuit Breaker
The Siemens 3RV6011-1GA15 is a SIRIUS motor protection circuit breaker, size S00, rated at 6.3 A operational current with a Class 10 trip characteristic. It combines a thermal overload release for sustained overcurrent protection and a magnetic short-circuit release for fault clearing, all in a 45 mm wide package that snaps onto 35 mm DIN rail per DIN EN 60715. Rated for 690 V AC at 50/60 Hz, this 3-pole breaker handles motor starting duty (AC-3) at up to 15 switching operations per hour. The 6 W typical power loss stays manageable in a closed panel, and the -20 to +60 °C operating range covers most industrial environments.
Mounting and Panel Fit
Mounts via screw fixing or snap-on onto 35 mm DIN rail (DIN EN 60715) in any orientation. The 45 mm width and 96 mm depth mean it fits standard S00-size cutouts; clearance requirements are 50 mm upward, 50 mm downward, and 30 mm to the side — no space needed forward or backward. Screw-type terminals on both main and auxiliary circuits accept 2x (0.5 to 1.5 mm²) solid/stranded or 2x (0.75 to 2.5 mm²) with ferrules; AWG equivalents are 2x (18 to 12) for mains and 2x (20 to 16) for auxiliaries. Terminal torque range is 0.8 to 1.2 N·m.
Lifecycle and Sourcing
RoHS compliance date is May 1, 2012, with substance prohibitance per EU directive. The part carries a 6 kV surge voltage resistance rating and passes 25g / 11 ms shock per IEC 60068-2-27, supporting typical industrial panel certification requirements.
What the Ratings Mean for Your Panel
The 6.3 A rated operational current and Class 10 trip class are sized for motor protection — Class 10 means the thermal element trips within 10 seconds at 7.2× rated current, matching standard IEC motor starting curves for pumps, fans, and compressors. The 690 V rated insulation voltage gives headroom for 400 V and 480 V systems with margin. The magnetic short-circuit release provides instantaneous fault clearing, while the thermal bimetal handles overloads. At 15 AC-3 operations per hour, this breaker is suited for normal motor starting duty, not high-cycle applications like rapid reversing.
