Siemens 3RV1011-0GA10-ZW98 — SIRIUS Motor Protection Circuit Breaker
The Siemens 3RV1011-0GA10-ZW98 is a SIRIUS motor protection circuit breaker with CLASS 10 trip and 100 kA breaking capacity at 400 V AC. Rated for the full range 20... 690 V, this unit includes phase failure detection — critical on motor loads where a lost phase can cause single-phasing and winding damage. The 45 mm width and 75 mm depth let it fit standard 35 mm DIN rail enclosures with screw and snap-on mounting per DIN EN 60715. Operating temperature range is -20... +60 °C, with storage and transport tolerance down to -50... +80 °C.
Panel Integration & Mounting
Mounts on 35 mm DIN rail per DIN EN 60715 using the combined screw and snap-on fastening method. Mounting position is any. Clearance requirements: 20 mm upwards, 20 mm downwards, 9 mm at the side, 0 mm forwards and backwards. The 45 mm width matches the standard SIRIUS 3RV1 footprint — it occupies one 45 mm module position on the rail. Screw-type terminals for the main current circuit accept 2× (0.5... 1.5 mm²) solid or stranded, or 2× (0.75... 2.5 mm²).
Coordination & Back-Up Protection
At 240 V and 400 V, no upstream fuse is required — the 100 kA breaking capacity handles fault clearance alone. At 500 V and 690 V, a gL/gG 6 A fuse is specified for back-up protection. The rated operational current at AC-3 maximum is 15 switching operations per hour.
