The 3-pole construction handles three-phase motor loads, and the integrated phase failure detection trips the breaker if one phase drops out, which prevents single-phasing damage to the motor windings. Breaking capacity is the headline number for an MCCB: this unit interrupts 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That puts it in the high-interrupting category — suitable for main or large sub-feed positions where fault current is substantial.
Motor protection features and auxiliary wiring
That alarm contact can drive a panel light or a PLC input to flag a fault condition immediately. There is no undervoltage release fitted as standard, and no ground-fault monitoring version. If UVR or GF protection is required, those are separate accessory additions. The breaker has no communication function onboard — it is a standalone protective device, not a smart breaker with integrated metering or networking.
Maximum power dissipation is 4 W, which is low enough that no special ventilation is needed in a typical enclosed panel — just standard thermal management. The trip indicator and voltage trigger are present, giving visual and electrical status of the trip condition.
