It carries an ETU850 electronic overcurrent release, which means the trip curve is programmable and the breaker can communicate status over a network — the communication function is built in, so you get remote monitoring without an add-on module. Four poles handle three-phase plus neutral, and the interrupting ratings are substantial: 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.
An optional motor drive is available as a field-installable accessory, which lets you remote-reset or remote-trip the breaker from a PLC or SCADA system.
The interrupting capacity at 690 V drops to 3.7 kA — still adequate for most secondary-side faults in a 690 V distribution board, but verify against your available fault current. Maximum power loss is 1.6 W, negligible for panel thermal budgeting.
