The real story is in the interrupting capacity: 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.
It's a panel-mount design typical of the SENTRON 3VA series — four-pole breakers this size take up a standard cutout and bolt directly to the mounting plate. The 140 mm width means it needs roughly 5.5 inches of horizontal space per unit. If you're swapping into a panel that was built around a different 4-pole 100 A MCCB, check the mounting centers and bus-bar takeoff points; the 86 mm depth usually clears standard gland plates and backpanel wiring troughs.
Thermal performance and operating range
Built-in communication and monitoring
This variant includes a communication function and ground-fault monitoring via summation current formation on L + N conductor. That means it can talk to a higher-level control system and detect ground faults by summing the phase and neutral currents — a practical feature for distribution panels where you want to know about leakage before it trips the main.
