What it is and what it does
The Siemens 3RV2011-1GA15-ZW96 is a SIRIUS motor protection circuit breaker with Class 10 trip protection, in a 45 mm wide package. Rated at 6.3 A at both 480 V and 600 V, with a 100 kA short-circuit current rating (SCCR) at 240 V, 400 V, and 500 V, this breaker can safely interrupt high-fault currents without upstream coordination issues in most industrial panels. Phase failure detection is built in — if one phase drops out, the breaker trips before the motor single-phases to failure.
Mounting and integration
Snaps onto 35 mm DIN rail per DIN EN 60715, or screws directly to a backplate. Mounting position is any orientation, which simplifies panel layout when space is tight. The 45 mm width (3 module spaces) and 97 mm depth fit standard distribution boards and motor control centers. Screw-type terminals on the main circuit accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded conductors, terminated with M3 screws. No special tooling needed — a standard PZ1 screwdriver handles the install. Clearance requirements: 50 mm above and below, 30 mm to the side, zero front and back — keeps the arc chamber vented and prevents heat buildup between adjacent breakers.
