It includes phase failure detection, which trips the breaker if one phase is lost, preventing single-phasing damage to the motor. Ground fault detection is not built in, so any ground-fault protection must be added upstream or in the drive.
Overall dimensions: 45 mm wide, 119 mm tall, 97 mm deep.
Short-circuit withstand and coordination
Rated short-circuit breaking capacity is 100 kA at 240 V AC, 25 kA at 400 V, and 2 kA at 690 V. For backup protection with upstream fuses, the table shows gL/gG fuse ratings: 63 A at 400 V, 50 A at 500 V and 690 V. That fuse size limits let-through energy so the breaker coordinates with a downstream contactor or starter.
