Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V — figures that put it in the high-fault-current bracket for industrial distribution panels where upstream transformer capacity or motor contribution drives available fault current above 100 kA.
At 40 °C the breaker holds 160 A continuous; derate to 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C — a 12% drop from 40 °C to 70 °C that matters when the MCCB sits in a sealed, uncooled enclosure near drives or transformers. Maximum power loss is 33 W at rated load, which should be factored into enclosure thermal calculations, especially in multi-breaker panels.
Rated insulation voltage is 800 V, and the operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C — covering most industrial environments from cold warehouses to hot panel interiors.
