It carries a TM210 thermal-magnetic overcurrent release — a fixed thermal element with magnetic short-circuit trip — and is rated for a maximum of 2 500 A interrupting capacity at the device level, with SCCR values that shift by voltage: 187 kA at 240 V AC, 121 kA at 415 V AC, 76 kA at 440 V AC, and 30 kA at 500 V AC. That SCCR curve tells you this breaker handles high-fault scenarios at lower voltages but derates significantly above 440 V — plan the upstream coordination accordingly.
Ratings that drive the fit
Continuous current rating holds flat at 250 A from 40 °C through 50 °C ambient, then steps down: 243.3 A at 55 °C, 236.5 A at 60 °C, 229.8 A at 65 °C, and 223 A at 70 °C.
Three-pole format, 105 mm wide by 158 mm tall by 70 mm deep — the 70 mm depth is shallower than many MCCBs in this class, so it tucks into a standard 200 mm deep enclosure with room for wiring gutters.
No official successor exists because none is needed.
