What this MCCB delivers and where it fits
The Siemens SENTRON 3VA1032-3ED36-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 32 A at 40 °C through 50 °C with no derating — it holds 32 A flat across that band, then steps down to 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 thermal curve means a panel at 50 °C ambient still gets full rated current; above that, the breaker self-protects. Interrupting capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — the 415 V figure is the one that matters for most European 400 V distribution panels, where it clears a 52.5 kA fault without cascading upstream. The TM210 overcurrent release (thermal-magnetic, fixed-trip) handles the overload and short-circuit protection; there is no voltage trigger, no phase failure detection, and no communication function on this variant. It ships with an undervoltage release (UVR) as the auxiliary release design, plus 2 auxiliary switches HQ (high-quantity) for status feedback to a PLC or annunciator. The integrated auxiliary trip order code is 3VA9608-0BB24. Front IP40 keeps out tools and debris in a clean panel; the latching endurance is rated at 15 000 operations.
Mounting and panel fit
Dimensions: 76.2 mm wide, 130 mm high, 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. The 70 mm depth means it clears most shallow enclosures; the 76.2 mm width matches the typical 3-module slot on a DIN rail. No trip indicator on the front, so fault isolation relies on the auxiliary switch feedback or a handheld IR scanner.
