It is fitted with a TM240 ATAM thermal-magnetic trip unit set at In=63 A, with adjustable overload protection Ir=44 A...63 A and short-circuit protection Ii=5...10 x In. The N-conductor is protected at 100%, and the unit includes a nut keeper kit; this variant is configured for DC Power OEM applications in China. For a 63 A frame, that is substantial headroom — it handles high prospective fault currents common in industrial distribution without needing an upstream current-limiting device. The adjustable Ir (44–63 A) lets you fine-tune the overload pickup to the actual load, and the Ii range (5–10 x In, so 315–630 A) sets the magnetic instantaneous trip point. The 100% N-conductor protection means the neutral pole is fully rated, not reduced — required on circuits where the neutral carries harmonic or unbalanced current. ## Deployment context The 4-pole configuration suits three-phase plus neutral distribution, and the DC Power OEM designation points to use in DC-side protection within power-conversion equipment — likely in Chinese-manufactured solar inverters, battery storage systems, or rectifier cabinets.","metaTitle":"Siemens 3VA1163-5GF42-0AA0-ZD00 Circuit Breaker, 63A, 55kA @","metaDescription":"Siemens 3VA1163-5GF42-0AA0-ZD00 IEC frame 160 MCCB, 4-pole, 63A, Icu=55kA @ 415V.
