The Siemens SENTRON 3VA1116-5ED32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current (Iu) with a TM210 thermal-magnetic overcurrent release. It's built for line protection — think main feeder or large subfeed in a distribution panel where you need a solid interrupting rating without communication or ground-fault add-ons. The interrupting ratings are what make this part stand out: 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 means it can clear a massive fault without blowing apart — useful where the transformer is right next to the panel and available fault current is high. At 415 V it still handles 121 kA, which covers most industrial low-voltage distribution. The TM210 release is a fixed thermal-magnetic type — no electronic adjustment, no communication module, no voltage trigger. It's a straightforward overcurrent protector: thermal for overload, magnetic for short-circuit. The auxiliary contact version is 4 HQ switches, so you get status feedback without needing a separate contactor block.
Sizing and thermal derating
Rated continuous current holds at 160 A from 40 °C up to 50 °C ambient. Above that it starts to step down: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. If your panel runs hot — say a packed enclosure with drives below — that 144 A at 70 °C is the number to size against, not the 160 A nameplate. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The IP40 front protection means it's fine in a clean indoor panel but not for washdown areas.
Panel fit and dimensions
Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall. That 76.2 mm width is three 25.4 mm pole spaces — standard for a 3-pole MCCB this size. Depth of 70 mm means it'll clear most backpanel wiring gutters without sticking out past the gland plate.
