Breaking capacity hits 330 kA at 240 V and 242 kA at 415 V, dropping to 7.5 kA at 690 V — that SCCR headroom covers transformer secondaries and large motor branch circuits without cascading upstream breakers. The ETU560 release supports adjustable N-conductor protection (OFF, 20% to 160%).
For a 40 °C panel, no derating needed — but if the enclosure runs hot from adjacent drives or transformers, factor the curve. The 3-pole frame mounts on a standard backplate or DIN rail adapter; front IP40 keeps out tools and dust in a closed cabinet. Maximum power loss is 96 W at rated current — budget that heat into the enclosure ventilation.
