What this MCCB carries — and what it doesn't
The 3VA1032-3ED36-0AC0: The 32 A rating holds flat from 40 °C through 50 °C, then derates in steps: 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. That means in a warm panel — say 50 °C ambient — you still get the full 32 A; you don't have to oversize the frame just because the enclosure runs hot. The interrupting ratings climb steeply as voltage drops: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. At 240 V this breaker handles a 75.6 kA fault without cracking — that's serious SCCR headroom for a 32 A frame. At 690 V the 7.5 kA rating tells you this is a 3-pole breaker wired for line-to-line 690 V, not a 4-pole unit with a fully rated neutral.
Panel fit and mounting
The 3VA1032-3ED36-0AC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The width is a standard 3-pole MCCB footprint — it fits the same DIN-rail or screw-mount hole pattern as other SENTRON 3VA frames, so swapping into an existing panel that was laid out for a 3VA1010 or 3VA1020 doesn't require re-drilling the backplate. Protection class on the front is IP40 — fine for a clean indoor panel, but not rated for washdown or outdoor exposure. The operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.
Auxiliary contacts and release options
This breaker ships with 2 auxiliary switches (HQ type) built in. It has no undervoltage release, no shunt trip (voltage trigger), no ground-fault monitoring, no phase-failure detection, and no communication module. The TM210 release is fixed thermal-magnetic — no adjustable long-time or short-time pickup curves. If you need adjustable electronic trip, you'd step up to the 3VA2 or 3VA3 series. Mechanical endurance is rated at 15 000 operations — that's the latching endurance, not the electrical switching life under load. For frequent switching applications you'd want to check the electrical endurance curve in the device manual.
