Its interrupting capacity reaches 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — covering most industrial fault-current scenarios without cascading upstream.
Thermal performance and ground-fault monitoring
Ground-fault monitoring uses summation current formation on the line conductor, which means it detects residual current by summing phase currents through a single core-balance transformer, simplifying wiring compared to separate CTs.
