The adjustable thermal-magnetic trip unit lets you set the instantaneous pickup anywhere from 600 A to 3000 A — that's 3× to 15× the continuous rating. On a motor circuit you'd typically dial it in above the locked-rotor current to avoid nuisance trips on start-up, but still low enough to clear a bolted fault fast.
Interrupting capacity — the real number
Interrupting capacity changes with system voltage, and this breaker delivers 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 5.2 kA at 690 V.
The breaker measures 181 mm high, 105 mm wide, and 86 mm deep — about 7.1 by 4.1 by 3.4 inches. No rewiring needed if you're replacing a same-footprint unit.
