The undervoltage release (UVR) is integrated at the factory, so if you need a UVR on the BOM, this order code already has it; no separate auxiliary release to order and snap in. Breaking capacity runs 187 kA at 240 V AC and 121 kA at 415/440 V, then drops to 79 kA at 500 V and 3.4 kA at 690 V. The 86 mm depth is the body-only dimension; factor in the rotary handle or extended-rotary operator if your enclosure depth is tight.
Above that it steps down: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C.
Auxiliary contacts and trip signaling
That gives you two form-C contacts for status feedback and a dedicated alarm contact that changes state only on a trip event — not on manual open/close. The integrated trip-alarm switch is wired to the ETU320's internal flag; no extra add-on block needed for remote trip indication.
