The Siemens 3VA1116-6GD42-0AA0-ZD00 is a 4-pole IEC frame 160 molded-case circuit breaker rated for line protection with a TM210 thermal-magnetic trip unit. Its headline figure is the 70 kA breaking capacity at 415 V (class H), which means it can safely interrupt fault currents up to that level without upstream coordination issues — critical for high-fault panels or transformer-fed switchboards where the available short-circuit current exceeds 50 kA.
Ratings and deployment
Fixed overload protection set at Ir = 160 A, with short-circuit pickup fixed at Ii = 10 × In (1600 A). The N-conductor protection is set to 100% — this breaker protects the neutral at full phase rating, which matters for panels feeding non-linear loads where neutral harmonics can exceed phase current.
