Siemens 3VA1110-5EE32-0AF0 — SENTRON MCCB, 100 A, Line Protection
The Siemens 3VA1110-5EE32-0AF0 is a SENTRON-series molded case circuit breaker (MCCB) rated for line-protection duty. 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. Three-pole design with a TM220 thermal-magnetic release, meaning the thermal element handles overloads and the magnetic element handles short-circuits. 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. Rated insulation voltage is 800 V, so it can be used in 690 V systems with adequate clearance. Max power loss is 25 W — factor that into your enclosure thermal calculation if you're packing multiple breakers in a small panel.
Sourcing & Lifecycle — Active Production, Quoted to Order
The auxiliary switch configuration is 1 auxiliary + 1 trip alarm switch (HQ type) — that's the factory-fitted option, so you don't need to order a separate accessory module for basic status feedback.
Panel Fit & Dimensions
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth. That 70 mm depth is the body depth — check your enclosure depth clearance, especially if you're mounting a door-mounted operator or a deep gland plate behind it. No undervoltage release, no communication function, no ground-fault monitoring on this variant. It's a straight line-protection MCCB with the TM220 release and the HQ auxiliary switch block. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. 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.
