The interrupting capacity scales with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That's a high-interrupting frame — suitable for fault currents near the transformer secondary where SCCR headroom matters. The shunt trip (STL) lets a safety PLC or E-stop circuit drop the breaker remotely without a handle — common in emergency-off chains or undervoltage-coordination schemes.
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint that fits Siemens SENTRON distribution blocks and DIN-rail adapters. The trip indicator is also absent — so fault indication relies on the shunt trip's auxiliary contact or a separate signal contact added to the breaker.
Above that it derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
