The interrupting capacity tells you where it can be applied: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V. It includes phase failure detection and an undervoltage release as built-in features, so it's ready for motor branch circuits where loss of a phase or a voltage dip needs to trip the breaker.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — the 105 mm width is standard for a 3-pole MCCB in this class, so it drops into existing SENTRON or comparable panel layouts without re-drilling. That covers unheated warehouses and outdoor cabinets in most climates.
