Breaking capacity is the headline: 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.
That's a standard 3-pole MCCB width for the 3VA frame — it fits the same DIN-rail or screw-mount pattern as other 3VA2010 variants. If you're swapping into an existing panel, check the depth clearance: 86 mm plus wiring space for the shunt trip terminals.
What the shunt trip means for your circuit
The shunt trip (STL) release lets you open the breaker electrically — apply a control voltage to the trip coil and the breaker opens regardless of load current. This is the standard way to integrate an MCCB into an emergency-stop chain or a remote shutdown system. The breaker itself does not include undervoltage release or ground-fault monitoring; those are separate accessory options if your application requires them.
Thermal performance across the panel ambient range
That's unusual for a molded case breaker; most frames start tapering above 40 °C.
