Built-in undervoltage release
No communication function or ground-fault monitoring is built in; this is a straight line-protection breaker with undervoltage and auxiliary contacts.
The 3VA1150-5EF36-0DC0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall. That 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for the SENTRON 3VA1 platform — it occupies three 25.4 mm pole spaces on a DIN rail or panel-mount base. The 70 mm depth leaves clearance for rear-mounted busbars or cable connections in a typical 600 mm deep enclosure. Power loss is 17.1 W maximum, which matters for thermal calculations in a sealed cabinet.
