Its headline figure is 100 A continuous current, and it holds that rating across the full operating temperature range from 40 °C to 70 °C — no derating needed as the panel warms up, which simplifies panel design. The 3-pole construction handles three-phase circuits, and the insulation voltage is rated at 800 V, so it covers 400/480 V systems with headroom. At 240 V it interrupts 187 kA; at 415 V and 440 V it still handles 121 kA. At 690 V the rating drops to 3.7 kA, so it is not the right choice for 690 V distribution without coordination study. The adjustable overload range runs from 150 A to 1 200 A, which means the 100 A frame is actually a 100 A continuous breaker with a wide trip-setting window. That range covers motor feeders and general distribution where you need to dial in the exact protection point.
The 3VA2110-5HL32-0AB0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures. The 86 mm depth is the dimension to check against gland-plate clearance or shallow backboxes; at 3.39 inches it usually clears a standard 200 mm enclosure depth. That keeps internal cabinet temperature rise manageable in a sealed enclosure, but if you stack several breakers in a small box, add up the dissipation and check the thermal rise.
