At 415 V and 440 V it still clears 187 kA, dropping to 121 kA at 500 V and 3.7 kA at 690 V. That 690 V figure is the practical limit for this pole count; above that you step to a higher-voltage frame. Three-pole construction, designed for line protection — meaning it's the main feeder breaker or a downstream distribution breaker, not a motor-protective device.
Panel fit and physical integration
The 86 mm depth (3.39 in) is shallow enough for 200 mm deep enclosures; verify gland-plate clearance for incoming cables if back-panel access is tight.
