The interrupting ratings are the headline spec here: 121 kA at 240 V AC, 75.6 kA at 415 V AC, 52.5 kA at 440 V AC, and 11.9 kA at both 500 V and 690 V AC. Current rating holds flat at 50 A from 40 °C through 50 °C ambient, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That flat plateau up to 50 °C is useful — many MCCBs start derating at 40 °C, so this one gives a bit more headroom in a warm panel before you have to oversize. This is normal for panel-mounted breakers; the IP40 rating means it's suitable for indoor switchgear and distribution boards where the enclosure provides the outer environmental seal. Maximum power loss is 14.6 W at rated current. It is a straight thermal-magnetic line-protection breaker — no auxiliary electronics. If you need shunt trip, UVR, or ground-fault signaling, you need a different suffix on the order code.","metaTitle":"Siemens 3VA1050-4ED32-0AA0 SENTRON MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1050-4ED32-0AA0 molded case circuit breaker, 50 A, 3-pole, TM210 release. 121 kA at 240 V, 75.6 kA at 415 V.
