Its interrupting capacity reaches 187 kA at 240 VAC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the 187 kA figure at 240 V means it can safely clear a fault at that level without upstream cascading, critical for high-available-fault-current services like transformer secondaries or large motor control centers.
Built-in auxiliary and communication
A communication function is integrated — the breaker can report status and trip events over a bus, reducing panel wiring and enabling remote diagnostics. Power loss is 6.5 W maximum, which keeps heat rise manageable in a densely packed enclosure.
Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — the 105 mm width is standard for a 3-pole MCCB in the SENTRON 3VA frame, so it fits existing panel cutouts and busbar spacing without modification. The trip indicator is present, giving a local visual signal after a fault event — useful for troubleshooting without a connected communication system.
