Its breaking capacity ranges from 242 kA at 240 VAC down to 3.7 kA at 690 VAC — the 242 kA figure at 240 V means it can safely interrupt a fault current up to that level without upstream devices needing to clear it, which is critical for high-fault locations like service entrances or transformer secondaries.
Thermal performance and derating
That's unusual for an MCCB; many competitors start dropping current above 40 °C. Maximum power loss is 4 W — negligible for thermal budgeting inside a crowded panel.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard SENTRON 3VA form factor that drops into the same mounting footprint as other 3VA frame sizes. The 86 mm depth means it fits shallow backpanels where a deeper MCCB would conflict with a rear door or busbar shroud. The basic switch variant is 3VA2163-6HL36-0AA0, so if you're replacing just the switching mechanism without the trip unit, that's the sub-assembly to order.
