Breaking capacity is specified across multiple voltage levels: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so the interrupting rating drops as system voltage rises, which is typical for MCCBs. At 415 V, the 32 kA figure covers most industrial distribution panels in common low-voltage networks. No auxiliary contact version is fitted, and there is no ground fault monitoring or N-conductor protection — this is a straight line-protection device with undervoltage trip capability.
Rated current holds at 50 A from 40 °C through 50 °C, then derates to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. In a sealed panel with poor airflow, that 45 A ceiling at 70 °C is the real limit — size the upstream conductor and downstream load accordingly. Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm high — a 4-pole MCCB footprint that fits standard SENTRON panel-mount cutouts. The 15 000 latching endurance cycles reflect the mechanical life of the switching mechanism — relevant for applications requiring frequent manual isolation.
