It carries an 80 A rated current at 40 °C, with a 3-pole configuration and a maximum breaking capacity of 52.5 kA at 240 V AC. Breaking capacity is voltage-dependent: 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Current derating and thermal performance
Above that, derating applies: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Maximum power loss is 19.2 W.
The 3-pole footprint is standard for this class of MCCB; verify the mounting hole pattern and busbar spacing against the existing panel layout before committing the BOM line.
