The Siemens SENTRON 3VA2110-7MN32-0BL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuously at 40 °C, with no derating needed up to 70 °C — the full 100 A holds across the ambient range, which simplifies panel sizing for warm enclosures. The interrupting capacity hits 330 kA at 240 V, tapering to 242 kA at 415/440 V and 187 kA at 500 V — enough for high-fault utility feeds or transformer secondaries.
Auxiliary switch complement and wiring
The UVR is the only auxiliary release fitted; there's no shunt trip or ground-fault module on this variant. Panel builders can land the alarm contacts directly into a PLC DI card without adding interposing relays.
