The Siemens 3RV1011-1HA15 is a SIRIUS motor-protective circuit breaker — a compact, current-limiting device sized for motor branch-circuit protection in control panels. Rated for operating voltages from 20 to 690 V, it covers common low-voltage motor circuits up to 690 V line-to-line.
Breaking capacity and backup protection
The interrupting rating hits 100 kA at 240 V, dropping to 13 kA at 400 V and 2 kA at 690 V. For high-fault installations, the evidence lists required upstream fuse backup: gL/gG 80 A at 240 V, 63 A at 400 V, 40 A at 500 V, and 40 A at 690 V. That means the breaker can be applied on systems with available fault current up to those levels, provided the specified backup fuse is in place.
Clearance requirements: 20 mm above and below, 9 mm at the sides, 0 mm forward and backward.
