For a 630A frame, 55kA at 415V gives solid selectivity headroom downstream; you can coordinate it with smaller branch breakers without worrying about cascading failures on a high-fault panel. ## Overload and short-circuit settings The TM220 trip unit provides adjustable overload protection (Ir) from 440A to 630A, covering the full In=630A rating. Short-circuit pickup (Ii) is fixed at 8 x In, or 5040A. The N conductor is protected at 100% of the phase rating — important for 4-wire systems where the neutral carries harmonic currents. This breaker also includes an ATFM (Advanced Thermal and Fixed Magnetic) characteristic, which means the thermal curve is adjustable but the magnetic instantaneous pickup is factory-set. This is a panel-mount breaker for IEC switchgear, typically installed in a distribution board or motor control center. The 4-pole configuration suits three-phase plus neutral systems common in commercial and industrial buildings. The nut keeper kit (included per the order code suffix) simplifies mounting in DC power OEM assemblies — it retains the mounting nuts during installation, a small time-saver on repetitive builds.","metaTitle":"Siemens 3VA1463-5GE42-0AA0-ZD00 Circuit Breaker, 630A, 55kA","metaDescription":"Siemens 3VA1463-5GE42-0AA0-ZD00 IEC frame 630 circuit breaker, 55kA breaking capacity at 415V, 4-pole, TM220 overload protection, Ir=440-630A, Ii=8xIn.
