It carries a 121 kA interrupting rating at 240 V and 75.6 kA at 415 V, so it handles high-fault-current service-entrance or distribution panels without cascading upstream — that's the spec that decides whether it clears a bolted fault or the main breaker trips instead. Rated continuous current Iu is 50 A, and it holds that rating from 40 °C up to 50 °C without derating — only drops to 48 A at 55 °C and 45 A at 70 °C. The interrupting ratings step down with voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. At 415 V it's still well above typical utility fault levels, so it's a clean fit for most European 400 V distribution. The TM210 release is thermal-magnetic — fixed thermal element for overload, magnetic for short-circuit — no electronic adjustment, which keeps it simple and reliable for standard line protection. The auxiliary trip module order code is 3VA9608-0BB25 if you ever need a replacement. Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep — that's a standard 3-pole MCCB footprint for a 50 A frame.","metaTitle":"Siemens 3VA1050-4ED32-0DH0 SENTRON MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1050-4ED32-0DH0 SENTRON molded case circuit breaker, 50 A, 3-pole, line protection, TM210 release, 121 kA at 240 V.
