What the ratings mean for fit
The 3VA1116-5ED32-0DH0 is a Siemens SENTRON molded case circuit breaker (MCCB) rated 160 A at 40 °C, 3-pole, designed for line protection. Its breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that tell you it can safely interrupt high fault currents without upstream cascading. The 160 A rating holds flat from 40 °C to 50 °C, then derates gradually to 150 A at 70 °C; that thermal curve matters if the breaker sits in a warm enclosure or next to other heat sources. The 800 V rated insulation voltage confirms it's built for 400 V class systems with headroom.
Panel integration and wiring
This MCCB occupies a 76.2 mm wide by 130 mm tall by 70 mm deep footprint — three standard 25 mm module widths on a DIN rail. The 3-pole body with built-in undervoltage release and two auxiliary switches plus one trip alarm switch means the kit ships complete: no separate add-on modules to chase. Power loss is 40.5 W maximum, so factor that into enclosure thermal calculations. Operating range spans -25 °C to 70 °C; storage from -40 °C to 80 °C.
