What the 160 A rating means for your panel
The Siemens 3VA1116-5ED46-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated 160 A at 40 °C — that's the continuous current it carries without tripping in a 40 °C ambient. The TM210 thermal-magnetic release handles overloads and short-circuits in one package. At 45 °C it still holds 160 A; at 55 °C it derates to 158 A, and at 70 °C it's 150 A, so if your panel runs hot, you lose 10 A off the top. Breaking capacity is the real fit question. This 4-pole unit clears 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. That covers most low-voltage distribution panels in North America (240/480 V) and Europe (400/415 V). The 690 V rating at 17 kA is useful for 600 V class Canadian panels or some industrial drives. Footprint is 70 mm deep, 101.6 mm wide, 130 mm tall — standard SENTRON 3VA form factor. Four-pole width at 101.6 mm means it occupies two 50 mm DIN-rail slots or a single wide cutout in a panel gland plate. IP40 on the front keeps fingers out but is not washdown-rated.
Integration notes
Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Insulation voltage rated 800 V. The part is designed for line protection (not motor protection — no overload class or phase-loss response). For motor branch circuits, pair it with a separate overload relay.
