What this MCCB carries — and what it doesn't
The 3VA1032-3ED36-0KC0: The interrupting capacity drops as line voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. That 690 V figure is the one to watch if you're feeding a 690 V motor control center — it's still serviceable for most downstream faults, but coordination studies should check the let-through at that level. Rated insulation voltage is 800 V. The front face carries IP40 protection.
Thermal derating and ambient limits
The 32 A rating holds from 40 °C through 50 °C. Above that it begins to taper: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If your panel ambient runs hot — say a crowded enclosure near a furnace line — factor that 28.8 A ceiling at 70 °C into your continuous load. Operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The storage limits matter if this sits in a cold warehouse before commissioning.
Integrated accessories and release options
This version ships with a shunt trip (STL) auxiliary release — part number 3VA9688-0BL33 — built in. That means you can remotely trip the breaker via a control signal, which is handy for emergency-stop circuits or remote disconnection schemes. It also carries 2 auxiliary switches (HQ type) for status feedback to a PLC or indication lamp. No undervoltage release, no ground-fault monitoring, no communication module, no phase-failure detection on this variant — if you need those, you're looking at a different suffix in the 3VA family.
Panel fit — dimensions and mounting
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep. No trip indicator on the front face; you'll rely on the auxiliary switch status or a visual check of the handle position.
