It uses a TM210 thermal-magnetic trip unit with fixed overload protection (Ir = 50 A) and fixed short-circuit protection set to 10 x In. The fixed Ir at 50 A means the overload pickup is non-adjustable; if your load draws more than 50 A continuously, the TM210 element will trip. The Ii = 10 x In (500 A instantaneous) handles motor starting inrush or transformer magnetizing currents without nuisance tripping, but it's not suitable for loads with very high inrush that exceed that multiple. The unprotected N conductor means the neutral pole has no overcurrent protection — it's a switched neutral only, common in 3-phase 4-wire distribution where the neutral is bonded at the source.","metaTitle":"Siemens 3VA1050-2ED42-0AA0-ZD00 Circuit Breaker, 50A, 16kA @","metaDescription":"Siemens 3VA1050-2ED42-0AA0-ZD00 circuit breaker, IEC frame 100, 4-pole, 50A, 16kA breaking capacity at 415V.
