What it is and what it delivers
The 3VA1112-3EF36-0AA0: Three poles, line protection design with a TM240 thermal-magnetic release. No undervoltage release, no communication function, no ground-fault monitoring — a straightforward feeder breaker for standard distribution.
What the ratings mean for your panel
Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall. That's the standard 3VA1 frame footprint. If your panel cutout is designed for a 3VA1 series, this breaker drops in without re-drilling. IP40 front protection keeps dust and fingers out of the mechanism in a typical enclosed switchboard. Power loss at maximum rating is 28.1 W. In a densely packed panel, that heat needs to be accounted for in thermal spacing; the breaker's own derating curve already assumes free air flow, so stack spacing matters. Rated insulation voltage is 800 V, which covers 690 V systems with margin. Storage temperature range is -40 to 80 °C; operating ambient is -25 to 70 °C. The storage range exceeds operating — that's a handling spec, not a running condition.
