Its breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V. The ETU560 trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection (summation current formation on L-conductor).
Above that it derates linearly: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. Max power loss is 5.4 W.
Dimensions and auxiliary contacts
No undervoltage release or voltage trigger; no phase failure detection. Communication function is present (likely via the ETU560's optional communication module, not integrated into the base breaker).
