The interrupting capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V.
Thermal derating — the real continuous current at panel temperature
At 55 °C it derates to 15.36 A, at 60 °C to 15.04 A, at 65 °C to 14.72 A, and at 70 °C to 14.4 A.
Panel fit — dimensions and mounting
The 70 mm depth means it clears most standard gland plates and shallow enclosures. The 3VA family uses a common footprint across the 16 A to 160 A range, so panel cutouts and busbar layouts transfer between frame sizes.
What the auxiliary configuration gives you
The factory-fitted auxiliary contact block provides 2 normally-open/normally-closed auxiliary switches plus a separate trip alarm switch. The trip alarm signals when the breaker has tripped on overload or short circuit — distinct from the aux switches that follow the main contact position. This matters for remote status monitoring: the trip alarm can trigger a PLC input or an alarm beacon independently of the breaker's on/off state. The shunt trip (STL) allows remote tripping via a control voltage; no undervoltage release is fitted.
