What this MCCB carries and where it fits
The Siemens 3VA1032-4ED36-0HA0 is a 3-pole SENTRON molded case circuit breaker rated for 32 A continuous current (Iu) at 40 °C, with a TM210 thermal-magnetic release and a shunt trip (STL) for remote opening. Its interrupting ratings climb to 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — numbers that govern selectivity and SCCR in the distribution panel, not just the breaker itself. The 70 mm depth and 76.2 mm width mean it fits the standard SENTRON 3VA mounting footprint; if you are swapping a failed unit on a live line, the dimensions match the existing bus-bar and DIN-rail cutout without re-drilling. This is a line-protection device — no undervoltage release, no auxiliary contacts, no communication module, no ground-fault monitoring. It is a straight thermal-magnetic MCCB with a shunt trip for emergency or remote disconnect, sized for a 32 A feeder.
Thermal derating and what it means for the panel
The 32 A rating holds flat from 40 °C to 50 °C. At 55 °C it derates to 30.72 A, at 60 °C to 30.08 A, at 65 °C to 29.44 A, and at 70 °C to 28.8 A. If the panel ambient runs above 50 °C, the continuous load must be trimmed or the breaker upsized. The TM210 release is the fixed thermal-magnetic element; there is no electronic adjustment or communication. For a panel-builder, that means the trip curve is set at the factory and the only field wiring is the shunt-trip coil (listed as 3VA9688-0BL30) plus the power terminals.
What this breaker does not include (and why that matters for a swap)
No trip indicator on the front face — if you need visual flag confirmation of a tripped state, this variant skips it. No auxiliary contacts either, so remote status monitoring requires an external accessory block. The shunt trip (STL) is factory-installed; verify the coil voltage matches the control circuit before wiring. The part carries IP40 protection on the front — fine for a dry indoor panel, not for washdown zones.
