What the ratings mean for your panel
The 3VA1110-5EE32-0AB0 is a Siemens SENTRON molded case circuit breaker (MCCB) sized for 100 A continuous duty at 40 °C, with a thermal-magnetic TM220 release. That 100 A holds flat through 50 °C — you only start derating at 55 °C (96 A), dropping to 90 A at 70 °C. For a 100 A feeder in a warm enclosure, that means no unnecessary upsizing unless ambient pushes past 50 °C. Breaking capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That 187 kA at 240 V is high — it handles fault currents from large transformers or parallel-fed busways without needing a current-limiting fuse upstream. At 690 V the 17 kA is modest; verify your available fault current if feeding a 690 V motor control center. The 3-pole frame carries a rated insulation voltage of 800 V, so it's rated for 690 V line-to-line systems. IP40 on the front means it's protected against tools and wires >1 mm — standard for a panel-mounted breaker, but not rated for washdown or outdoor exposure.
Panel fit and integration
The 3VA1110-5EE32-0AB0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep. That 76.2 mm width is a standard 3-pole MCCB footprint for this current class — it fits the same panel cutouts as other SENTRON 3VA1 breakers. The 70 mm depth leaves room behind the door for wiring gutters or busbar connections. It ships with 2 auxiliary switches (HP type) pre-installed, but no undervoltage release, no shunt trip, no ground-fault module, and no communication function. If you need remote trip or status feedback beyond the aux contacts, you'll add those as separate accessories. The TM220 release is fixed thermal-magnetic — no electronic adjustment curves.
