For a 63 A breaker, that's generous headroom; you'd typically see 25–36 kA at this frame size, so this unit is suited for high-fault-capacity panels where upstream coordination demands a stiff interrupting rating. The TM220 trip provides adjustable overload protection (Ir from 44 A to 63 A) via a rotary dial, and fixed instantaneous magnetic pickup at 10 x In (630 A). The 'ATFM' designation indicates the trip unit type — thermal-magnetic with fixed magnetic, adjustable thermal. The 100% N-conductor protection means the neutral pole is fully rated, not reduced, which matters for harmonic-rich loads or where the neutral carries near-phase current. ## Deployment context The 'nut keeper kit for DC Power OEM in China' note suggests this variant was configured for a specific OEM build — the kit retains mounting hardware during transport and installation. For a panel builder, that means the breaker ships with captive nuts for the busbar connections, saving a few minutes per unit on the assembly line.","metaTitle":"Siemens 3VA1163-4GE42-0AA0-ZD00 IEC Breaker, 63A, 36kA","metaDescription":"Siemens 3VA1163-4GE42-0AA0-ZD00 IEC frame 160 MCCB, 36kA @ 415V, 4-pole, TM220, In=63A.
