What this MCCB delivers in the panel
The Siemens SENTRON 3VA2163-7MS32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuously across the full 40 °C to 70 °C ambient range — no derating needed as the cabinet warms up. Its interrupting capacity hits 330 kA at 240 V and still holds 242 kA at 415 V, so it handles high-fault-current points like main feeders or large motor branch circuits without cascading upstream breakers. This is the starter-protection variant (design of the product: starter protection), meaning it's tuned for motor-starting inrush and overload profiles — a common fit for pump, fan, or compressor branch circuits where you want coordinated protection between the MCCB and a downstream contactor/overload.
Undervoltage release and control wiring
The breaker ships with an undervoltage release (UVR) fitted — design of the auxiliary release is undervoltage release (UVR). That UVR will trip the breaker if control voltage drops below a set threshold, which is standard for safety circuits that need to drop a motor on loss of control power. No auxiliary switch is included; if you need status feedback to a PLC or pilot light, order the auxiliary switch block separately. Panel space: the breaker occupies 105 mm width × 181 mm height × 86 mm depth — a standard 3-pole MCCB footprint that fits most SENTRON mounting bases and DIN-rail adapters.
