It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, and 75.6 kA at 500 V — numbers that define the fault-current headroom for the downstream network.
Ground-fault monitoring uses summation current formation on L + N, meaning it detects leakage by summing phase and neutral currents; this is a residual-current style detection built into the MCCB, not a separate module.
Dimensions are 181 mm high, 140 mm wide, 86 mm deep — a 4-pole footprint that matches the standard SENTRON 3VA frame. No communication module or undervoltage release is built in, so any auxiliaries (shunt trip, alarm switch) must be added externally.
