The magnetic trip adjustable 5–15 x In covers motor-start inrush without nuisance tripping; there is no thermal overload element, so a separate overload relay must be wired downstream for motor protection. The magnetic-only release (TM120M) provides short-circuit and ground-fault protection only; since In = 63 A and the thermal element is omitted, it relies on a separate overload relay for motor thermal protection. The 2 auxiliary switches (HQ) and nut keeper kit are factory-fitted, saving panel-builder wiring time.","metaTitle":"Siemens 3VA1163-6MH32-0AC0 Circuit Breaker, 70kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-6MH32-0AC0 IEC frame 160 breaker, 70kA Icu @ 415V, 63A TM120M magnetic-only.
