Breaking capacity reaches 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V — the 690 V figure is the limit for this frame, so verify SCCR against your transformer secondary or generator fault current.
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — the 138 mm width is the standard 3-pole MCCB footprint for this SENTRON frame, so it drops into existing panel cutouts and busbar arrangements sized for the 3VA2 platform.
Yes, it includes a shunt trip release (STL) for remote tripping and two HQ auxiliary switches for status indication.
