The Siemens 3VA1180-4GF42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker in the 3VA1 series, rated at 80 A with a breaking capacity class S — Icu of 36 kA at 415 V. That 36 kA interrupting rating at 415 V means it can safely clear a fault up to that level without upstream cascading, which is the figure that governs panel SCCR coordination in IEC 60947-2 applications. The TM240 thermal-magnetic trip unit gives adjustable overload protection (Ir = 56 A to 80 A) and fixed short-circuit protection (Ii = 5 to 10 x In), so you set the pickup to match the downstream cable or load without swapping the breaker body.
This breaker mounts on a DIN rail in the panel enclosure. The 4-pole configuration with N-conductor protection at 100% means the neutral pole is switched and protected at the same rating as the phase poles — important for 4-wire systems where the neutral carries load current, not just fault current. The nut keeper kit included indicates it is prepared for DC Power OEM builds in China, where captive hardware prevents loosening under transport vibration.
