Siemens 3VA1216-6EE42-0AA0-ZD00 Circuit Breaker, 160A, 70kA

The Siemens 3VA1216-6EE42-0AA0-ZD00 is a 4-pole IEC frame 250 molded-case circuit breaker rated 160 A continuous, with a 70 kA interrupting capacity at 415 V — breaking capacity class H. Overload protection is adjustable via the TM220 thermal-magnetic trip unit: Ir from 112 A to 160 A, so you dial in the actual load current. Short-circuit protection is fixed at Ii = 10 × In (1600 A), which is a magnetic-only instantaneous trip — no ground-fault or short-time delay on this variant. The N conductor is unprotected, meaning the neutral pole is not monitored or switched; this breaker is for line-side protection only. The form factor is standard for a 4-pole 3VA1 frame.
