What this 3VA2 frame delivers
The Siemens 3VA2116-6HM36-0AA0 is a SENTRON molded case circuit breaker (MCCB) in a 3-pole, 160 A continuous-current configuration, fitted with an ETU330 electronic trip unit and designated for line protection duty. Rated insulation voltage Ui is 800 V, and the interrupting capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — giving the breaker substantial fault-clearing headroom across common industrial voltage levels. The 160 A rating holds flat across the full operating temperature range from 40 °C to 70 °C, so no derating is needed for warm enclosures up to that limit. Maximum power loss is 25.5 W, and front-face protection is IP40 — suitable for panel-mount applications where the breaker is behind a closed door.
Dimensions and panel fit
The breaker occupies 105 mm width, 181 mm height, and 86 mm depth (4.13 × 7.13 × 3.39 in), which is the standard 3VA2 frame footprint for this current class. Mounts on a DIN rail or direct-panel via the 3VA accessory kit; the 86 mm depth leaves room for rear-connected busbars or cable lugs in a typical distribution panel.
