The IP20 front protection keeps fingers away from live parts — finger-safe touch protection is built in. Operating temperature range is -20 to +60 °C, storage -50 to +80 °C, and it withstands 25g shock at 11 ms, so it's fine for conveyor lines or machine tools with vibration. The 22 A continuous current rating is the thermal current the breaker can carry indefinitely without tripping. The operating voltage max is 690 V, so it works on 400 V, 480 V, and 690 V systems. Breaking capacity varies with voltage: 100 kA at 240 V, 50 kA at 400 V, 10 kA at 500 V, and 4 kA at 690 V. For a 400 V panel with a 50 kA available fault current, this breaker is a direct fit. The power loss in hot operating state is 10.5 W total, 3.5 W per pole — useful for thermal management inside a sealed enclosure. It has three poles for the main circuit and accepts an auxiliary switch (product extension auxiliary switch: yes). No ground fault or phase failure detection built in — those functions are handled by the upstream motor starter or a separate monitoring relay. The maximum operating frequency at AC-3 is 15 operations per hour, so it's suited for intermittent duty, not high-cycle applications like rapid reversing. Solid and stranded wire acceptance: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²) per terminal. AWG equivalents: 2x (14 to 10) for main contacts. Finely stranded with core end processing also accepted in the same ranges. No backwards or side clearance required — 0 mm spacing — so you can mount multiple units side by side without extra gap. Mounting position any orientation. Dimensions: 45 mm wide, 97 mm high, 96 mm deep. That's a standard 45 mm module width, so it occupies one slot on a DIN rail. The depth of 96 mm means it projects about 96 mm from the rail — check enclosure depth if you're retrofitting into a shallow panel. For volume purchases or blanket orders, submit an RFQ — we can provide compliance documentation (RoHS substance prohibition date 01.05.2012, REACH, UL, IEC) with the quote.","metaTitle":"Siemens 3RV1321-4CC10 SIRIUS Circuit Breaker, 22 A, 11 kW at","metaDescription":"Siemens 3RV1321-4CC10 SIRIUS circuit breaker for starter combinations. 22 A continuous, 11 kW at 400 V, 50 kA breaking at 400 V.
