What the ratings mean for fit
The Siemens 3VA1163-6MH36-0AE0 is a 3-pole IEC frame 160 circuit breaker with a 63 A rated current and a 70 kA breaking capacity at 415 V (class H). The high Icu means it can safely interrupt fault currents up to that level without upstream cascading — critical for selectivity coordination in a distribution panel where the main breaker is rated higher. The TM120M trip unit provides starter protection (motor-starting duty), but note this variant ships without overload protection: the TM120M handles short-circuit only (Ii adjustable 5...15 x In). You'll need a separate overload relay upstream if the load is a motor. The four auxiliary switches (HQ) allow status feedback to a PLC or HMI — useful for remote indication or safety interlocks. Clamp-type terminals accept standard copper conductors; no lugs required for panel wiring.
Deployment context
Mounts on a DIN rail inside a standard IP54 or higher enclosure — typical for industrial motor control centers (MCCs) or distribution boards. The clamp terminals and compact 3VA1 footprint simplify panel integration; the four auxiliary switches reduce the need for separate contact blocks.
