The interrupting capacity tells you where it can live: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — that high 330 kA figure at 240 V means it handles a strong fault upstream without needing a current-limiting fuse ahead of it.
Motor protection features
This MCCB includes phase failure detection — if one phase drops out on a three-phase motor, the breaker trips before single-phasing cooks the winding. It also carries an undervoltage release (UVR) that drops the breaker if supply voltage falls below a threshold, so the motor doesn't re-accelerate uncommanded after a brownout. Trip indicator is present, so you can tell at a glance whether the breaker tripped on fault or was switched off.
Power dissipation at rated load is 12.5 W maximum — negligible for thermal panel calculations unless you pack a dozen in one enclosure.
