What this 3VA2 frame delivers
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. 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.
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.
