MCCB for high-fault panel applications
It's built to handle serious fault current: 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you this breaker is meant for high-available-fault-current panels where a standard MCCB would weld its contacts shut.
Above that it derates linearly: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C. The case dimensions are 130 mm high by 76.2 mm wide by 70 mm deep, and it carries an IP40 front protection rating, so it's fine for general indoor panel mounting but not for washdown areas. No auxiliary contacts, no communication module, no undervoltage release — this is a bare-bones line-protection breaker with a shunt trip for remote opening.
