The Siemens 3VA1163-6GF42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker rated for line protection with a breaking capacity class H — 70 kA at 415 V. That's the high-interrupting variant, sized for industrial panelboards and distribution where fault currents can hit that level without cascading upstream. The thermal-magnetic trip unit (TM240, ATAM) gives you overload protection adjustable from 44 A to 63 A and short-circuit protection set at 5 to 10 times In. The neutral conductor is protected at 100% of the phase rating, and the unit includes a nut keeper kit — a detail that saves time during DC Power OEM builds in China, where this variant is specified.
