It carries an interrupting capacity of 330 kA at 240 V and 242 kA at 415 V, dropping to 3.7 kA at 690 V. The breaker includes an undervoltage release and phase failure detection, with a built-in trip indicator and a 2-auxiliary-switch plus 1-trip-alarm-switch configuration. Maximum power dissipation is 12.5 W.
The 330 kA interrupting capacity at 240 V is the headline figure for fault clearing; at 690 V it drops to 3.7 kA, so verify system voltage against the SCCR curve. The 3-pole design with motor protection curve means it's sized for a three-phase motor load, not a feeder or distribution bus. The undervoltage release (UVR) and phase failure detection are built in, so no external monitoring relay is needed for those functions.
