Rated continuous current Iu is 80 A, and the breaker holds that rating across the 40 °C to 50 °C ambient band without derating; at 55 °C it steps down to 76.8 A, and at 70 °C it reaches 72 A — useful to know if the panel runs hot or sits near other heat sources. Breaking capacity is specified at four voltage levels: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. The overcurrent release is a TM210 — a thermal-magnetic fixed-trip design, not an electronic one, so there is no adjustable long-time or short-time pickup. That simplifies specification: you get a fixed 80 A thermal element and a magnetic instantaneous trip set at 10× Iu (800 A).
Mounting and integration — what fits where
The 3VA1080-4ED32-0JA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. Front-face protection is IP40. The shunt trip (STL) is included as the design of the auxiliary release — this allows remote tripping via a control voltage, which is typical for emergency-stop circuits or interlocking schemes. No undervoltage release is fitted, so the breaker will not automatically open on loss of control power; if that function is needed, the ordering code would differ.
