Breaking capacity is the headline spec here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That high interrupt rating at 240 V makes this breaker a strong candidate for high-fault service entrance or sub-distribution where available short-circuit current exceeds 100 kA — common in large industrial plants or utility tie points. Current derating is published across the full ambient range: 160 A up to 50 °C, then 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that drops into SENTRON 3VA mounting bases and busbar adapters without modification. If those are needed for the application, they must be added externally via the 3VA accessory system — the breaker itself is a straight thermal-magnetic line-protection device.
