That's a serious short-circuit rating for a 50 A line protection breaker, sized for industrial panelboards and motor control centers where high available fault current is a real hazard. The TM220 thermal-magnetic trip unit gives you adjustable overload protection from 35 A to 50 A, and a fixed short-circuit pickup of 10 times the rating (Ii = 10 x In). The 'N conductor unprotected' note means the neutral pole has no overcurrent protection — it switches but doesn't trip, which is standard for many 3-phase, 4-wire distribution schemes where the neutral is sized to carry unbalanced load only. That's class H breaking capacity — the highest standard tier for the 3VA1 frame. The 4-pole construction with unprotected neutral fits European and Asian distribution practice where the neutral is switched but not fused. The adjustable thermal overload (Ir = 35–50 A) lets you dial it to the exact motor FLA or feeder load without swapping trip units. Fixed magnetic pickup at 10x In means it holds through motor inrush without nuisance tripping on a standard Design B motor start.","metaTitle":"Siemens 3VA1150-6EE42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1150-6EE42-0AA0-ZD00 IEC frame 160 circuit breaker.
