What this order code delivers
The Siemens 3VA1163-6MH32-0DA0 is a 3-pole IEC frame 160 circuit breaker with a 63 A rating and a class H breaking capacity of 70 kA at 415 V AC. The breaker is configured for starter protection with a TM120M thermal-magnetic release, adjustable short-circuit pickup from 5 to 15 x In, and includes an undervoltage release (UVR) rated 208-230 V AC, 50/60 Hz.
What the configuration means for the panel
The nut keeper kit is factory-fitted, which simplifies DIN-rail mounting in a panel — no loose hardware to lose during assembly. Note that this variant omits overload protection; the TM120M release handles short-circuit only. Overload coordination must be handled by a separate thermal overload relay or motor-protective device downstream.
