MCCB for line protection with high interrupting capacity
Its interrupting capacity reaches 220 kA at 240 V AC, dropping to 154 kA at 415 V and 121 kA at 440 V — figures that cover most industrial fault-current scenarios without cascading upstream.
Thermal derating and auxiliary configuration
That matters when the MCCB sits in a crowded enclosure — the 27.5 W maximum power loss adds to the internal heat load. No ground-fault monitoring or communication module is included.
The 3VA1110-6EF32-0CH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that mounts on a DIN rail or panel-mount adapter. The 70 mm depth leaves clearance for rear-connected busbars in a typical distribution board.
