The Ii range of 5–10× In (500–1000 A magnetic pickup) gives flexibility for inrush from motor starters or transformers; set it high enough to avoid nuisance trips on start-up, low enough to clear a bolted fault fast. This is a DIN-rail-mount MCCB, sized for a standard 3-pole footprint in a distribution board or motor control center. The clamp terminals accept copper or aluminum conductors up to the frame's rated cross-section — no lug kit needed for most panel builds. Wire the UVR supply through a normally-closed contact from an upstream safety relay if you need a coordinated emergency-off chain.","metaTitle":"Siemens 3VA1110-4EF36-0CA0 Circuit Breaker, 100A, 36kA @ 415","metaDescription":"Siemens 3VA1110-4EF36-0CA0 IEC frame 160, 3-pole, 100A, Icu=36kA @ 415V, TM240, UVR 120-127V AC.
