What this MCCB carries — and where it stops
The Siemens SENTRON 3VA1132-5EF36-0AD0 is a 3-pole molded case circuit breaker rated for 32 A continuous at 40 °C, with a TM240 thermal-magnetic release that holds steady through 50 °C before the thermal curve starts to pull back — 30.72 A at 55 °C, 29.44 A at 65 °C, 28.8 A at 70 °C. That derating profile matters if this lands in a crowded panel or a warm enclosure; the 32 A nameplate is good only up to 50 °C ambient. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That's a lot of fault-current headroom for a 32 A frame — it'll ride through a high-available-fault panel without cascading upstream. The 800 V rated insulation voltage (Ui) backs it for 480/277 V or 600 V delta systems. Line protection version, no undervoltage release, no ground-fault monitoring, no communication module. Three auxiliary switches (HQ type) come built in. IP40 on the front — fine for a dry indoor panel, not for washdown.
Panel fit — the 70 mm depth matters
Footprint is 70 mm deep by 76.2 mm wide by 130 mm tall. That 70 mm depth is shallow enough for most 200 mm deep enclosures with the door closed; the 76.2 mm width (roughly 3 inches) is a standard 3-pole MCCB slice. Mounts on a DIN rail or direct-panel with the SENTRON base adapters. Three auxiliary switches HQ are already on the side — no add-on module needed for status feedback.
