Three-pole construction with phase failure detection built in. The interrupting ratings are what you need for a high-fault installation: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V (–). A trip indicator and undervoltage release option (not fitted here) round out the signal package for remote status and lockout schemes.
Breaking capacity and motor protection duty
Rated 160 A continuous, and the design is motor-protection — meaning the thermal-magnetic or electronic trip curve is shaped for motor inrush and overload profiles, not straight feeder protection. Power loss at rated load is 19.7 W maximum — relevant for enclosure thermal calculations when grouping multiple breakers.
Panel integration and compliance
The 86 mm depth fits standard 200 mm deep enclosures with clearance for rear-connected busbars. The part carries a trip indicator for visual fault identification without opening the panel.
