Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — enough headroom for most industrial distribution panels where fault currents can spike during a bolted fault. The 32 A rating holds steady from 40 °C up to 50 °C, then derates gradually to 28.8 A at 70 °C — meaning you can pack it into a warm enclosure without losing much capacity.
At 76.2 mm wide, 130 mm tall, and 70 mm deep, this breaker fits standard 3-pole MCCB footprints — no surprises when swapping into an existing SENTRON or third-party panel.
