Thermal stability across the operating band
The 3VA2110-5HL32-0AA0: Continuous current holds at 100 A from 40 °C up to 70 °C ambient with no derating; the ETU320 release stays calibrated within that span. Running near a furnace wall or in a hot enclosure won't shift the trip curve.
Physical dimensions and panel fit
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. Front face is IP40-protected. It occupies a standard 3-pole MCCB footprint, compatible with SENTRON panel-mounting hardware.
