Key ratings and what they mean for your panel
The Siemens 3VA1110-5EE32-0AD0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current with a TM220 thermal-magnetic release — meaning the thermal element is fixed at 100 A and the magnetic pickup is adjustable around 220 A, covering motor-start inrush and feeder protection in a single frame. Its interrupting capacity is the headline figure: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. At 415 V — the common European industrial distribution voltage — 121 kA SCCR means this breaker can safely clear a fault up to that level without upstream fuses needing to operate, which simplifies selectivity coordination in a main or sub-feed position. Thermal derating is modest: the breaker carries a full 100 A from 40 °C through 50 °C, then drops to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If your panel ambient runs above 50 °C, size the load at the derated value — the TM220 release's thermal element tracks ambient, so you won't nuisance-trip on a hot day if you stay under the curve.
Fit and integration details
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that mounts on a DIN rail or panel-mount base. The IP40 front protection means it's suitable for enclosed panel installation where no water jets are present; the terminals are protected by the enclosure door. It ships with 3 auxiliary switches (HQ — high-qualified, meaning high-reliability contacts for signal feedback) but no undervoltage release, no shunt trip, no ground-fault monitoring, and no communication module. If you need remote trip indication or a UVR for safety circuits, you'll add those as external accessories or choose a different version. Rated insulation voltage is 800 V, so it's comfortable on 690 V systems with proper clearance. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
