The Siemens SENTRON 3VA2110-5KP32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415/440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V — so at typical 400 V industrial feeds it clears faults up to 121 kA without cascading upstream breakers. The 100 A rating holds flat across the full operating temperature range from -25 °C to 70 °C, meaning no derating is needed for warm enclosures or outdoor cabinets within that band.
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without gland-plate modification. It ships with two auxiliary switches (HQ type) and an undervoltage release (UVR) integrated, so the auxiliary contact block and shunt-trip wiring are already accounted for in the panel layout. No separate UVR module to mount alongside.
