Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V, dropping to 52.5 kA at 440 V and 11.9 kA at 690 V. That means it can clear high-fault currents on a 240 V distribution bus without upstream coordination issues — the 121 kA figure is what drives the SCCR on a panel label. That UVR is a key detail for any panel where a loss-of-voltage condition must trip the breaker automatically, typical in safety circuits or motor-control centers with undervoltage protection schemes.
At 55 °C it derates to 24 A, at 60 °C to 23.5 A, and at 70 °C to 22.5 A. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth; the 76.2 mm width is a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount bases without re-drilling.
