The interrupting capacity is the headline: 440 kA at 240 V, 242 kA at 415/440 V, 154 kA at 500 V, and 17 kA at 690 V. The 4-pole design (switching all three phases plus neutral) is standard for TN-S or TN-C-S systems where the neutral needs protection or isolation.
Full 500 A rating holds up to 50 °C ambient. Above that it derates: 488 A at 55 °C, 476 A at 60 °C, 464 A at 65 °C, 452 A at 70 °C. The TM220 release is a fixed thermal-magnetic type — no interchangeable trip units, so the 500 A setting is baked in. Power loss at rated load is 122.7 W maximum — plan for that heat in your enclosure thermal budget.
Dimensions: 184 mm wide, 248 mm high, 110 mm deep. That 184 mm width on a 4-pole 500 A frame is the critical number for panel layout — it determines the DIN-rail or mounting-plate pitch and whether it fits alongside existing breakers in a multi-column switchboard. No communication function on this unit; it's a straight electromechanical breaker with no Modbus or PROFIBUS interface.
