Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V, so it clears high-fault currents across common low-voltage networks without cascading upstream.
Ratings in context
The interrupting ratings at 240 V (187 kA) and 415 V (121 kA) cover the typical fault-current levels at a service entrance or downstream sub-distribution board.
Built-in accessories
If those are needed, a different 3VA variant or an external relay is required.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON panelboards and third-party enclosures with a 105 mm module pitch.
