What the ratings mean for fit
The 3VA2010-6HL32-0KH0: The 100 A rating holds flat from 40 °C through 50 °C, then derates to 85 A at 70 °C — so in a warm panel (say 55 °C ambient) you still get 96.25 A continuous. That thermal curve is what a panel builder uses to size the breaker without overspending on copper. The 242 kA at 240 V and 187 kA at 415 V are the interrupting ratings; for a 480 V system the relevant figure is the 500 V line (121 kA), and at 690 V it drops to 4 kA — a reminder that this breaker is built for low-voltage distribution, not 690 V motor circuits. The shunt trip (STL) release is built in — design code 6HL32 signals that. Auxiliary contact configuration is 2 auxiliary switches plus 1 trip alarm switch (HQ), which gives the control system both a status mirror and a separate fault signal. No undervoltage release, no ground-fault monitoring, no communication module on this variant. It is a straightforward line-protection MCCB with remote trip capability.
Dimensions and panel fit
Footprint is 105 mm wide × 181 mm high × 86 mm deep — a standard 3-pole MCCB envelope that drops into most SENTRON 3VA2 mounting plates and busbar systems. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Max power loss at rated current is 13.5 W, which factors into the enclosure thermal budget.
