The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V and at 440 V, 79 kA at 500 V, and 3.4 kA at 690 V. The 63 A frame holds that rating steady from 40 °C up to 50 °C; above that it derates to 60.6375 A at 55 °C and down to 53.55 A at 70 °C.
Trip unit and auxiliary hardware
There is no phase failure detection and no voltage trigger on this variant. Communication function is present — the ETU560 supports optional communication modules for remote monitoring, though the base breaker does not include a module in the order code.
The breaker is designed for panel mounting, typically on a mounting plate with busbar connections. No trip indicator is fitted on this variant — you will need to check the ETU560 display or auxiliary contacts for status.
