The ETU350 electronic trip unit gives adjustable long-time, short-time, and instantaneous pickup, so you can tune coordination with downstream breakers. Three poles cover three-phase circuits.
The 3VA2140-0HN36-0AA0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA2 frame footprint. It mounts via screw terminals or plug-in base (depending on the accessory selected) into a switchboard or enclosure. The IP40 front protection means the breaker face is protected against tools and solid objects over 1 mm, but the enclosure itself must provide the overall panel IP rating.
