Siemens 3VA1110-5EE32-0AF0 — SENTRON MCCB, 100 A, Line Protection
It carries 100 A continuously at ambient temperatures up to 50 °C without derating — only a 2 A drop at 55 °C and 9 A at 70 °C, which gives you real headroom in a warm enclosure. The trip indicator is built in — no need to add a separate flag. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That covers most industrial distribution panels where fault current is high at the main incoming point.

Panel Fit & Dimensions
It's a straight line-protection MCCB with the TM220 release and the HQ auxiliary switch block. The 70 °C operating max matches the top of the derating curve — if your panel ambient pushes past that, you need to derate further or move to a higher-frame breaker.
Peer Comparison — 3VA1110-5ED36-0AC0 vs This Unit
The closest functional peer is the 3VA1110-5ED36-0AC0. The key difference is the overcurrent release: this unit (5EE32) uses a TM220 release, while the 5ED36 variant uses a different release characteristic. Both are 3-pole, 100 A, SENTRON line-protection MCCBs with the same physical footprint — same height, width, and depth — so they drop into the same panel cutout and bus connections without rewiring. If your BOM specifies the TM220 release curve, the 5EE32 is the correct fit. The 5ED36 has a different trip curve and may not coordinate with downstream breakers the same way. Verify the release type on your existing panel schedule before substituting.
