The Siemens SENTRON 3VA2163-5KP32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 63 A at ambient temperatures from 40 °C through 70 °C — no derating needed across that range, which simplifies panel design in warm enclosures. Its breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. It carries a communication function, so it can report status or trip events to a PLC or BMS over the auxiliary switch interface. The auxiliary switch design accommodates 4 HQ auxiliary switches, letting you wire separate signals for trip indication, remote status, and interlocking without adding external relay blocks.
Deployment context
The 3-pole form factor and 105 mm width match standard busbar and cable lug spacing. The communication function and 4 auxiliary switch slots make it suitable for integration into a monitored distribution system where the MCCB reports its state to a higher-level controller.
