That SCCR curve matters when you're coordinating with upstream protective devices in a panel — you can size the feeder breaker knowing this device will interrupt faults up to those levels without cascading. ## Ratings That Drive the Selection The 50 A continuous current rating is the thermal through-current — this is what governs the conductor sizing and the upstream protection coordination. The 22 kW at 400 V is the motor output it can protect in AC-3 duty (starting and stopping a squirrel-cage motor under load). The switching frequency is 15 operations per hour at AC-3 — fine for a pump or fan start, not for a high-cycle indexing table. Power dissipation runs 29 W total in hot operating state, or 9.7 W per pole; that heat has to be considered in a sealed enclosure derating calculation. Wire range: solid conductors accept 2x 0.75…16 mm²; stranded accepts 2x 0.75…25 mm² or single up to 35 mm². That covers most motor feeder cables up to 50 A. The screw-type box terminals are standard for the main circuit; auxiliary contacts use separate screw terminals. The unit supports an auxiliary switch extension — you can add a signal contact for remote status indication without replacing the breaker. ## Integration and Environmental Limits Mounting position is any orientation — no derating needed for horizontal or vertical rail placement. Shock resistance is 25 g for 11 ms — survives typical panel shipping and machine vibration. Surge voltage withstand is 6 kV, which covers overvoltage category III in a 400 V distribution system. Finger-safe touch protection means no exposed live parts when the front cover is on — meets the basic safety requirement for IP20 enclosures.","metaTitle":"Siemens 3RV1331-4HC10 SIRIUS Circuit Breaker, 50 A, 22 kW at","metaDescription":"Siemens 3RV1331-4HC10 SIRIUS circuit breaker for starter combinations. 50 A continuous, 22 kW at 400 V, 50 kA SCCR.
