Product details

SIRIUS S00 direct starter — 4 A AC-3, CLASS 10

The 3RA2115-1EA16-5BB4: The unit ships with a 3RT2016-1BB44 contactor and a 3RA1921-1DA00 link module pre-assembled — the contactor and overload are matched at the factory, so the coordination between the bimetal trip and the contactor weld withstand is already validated.

Panel fit — DIN rail footprint and clearances

Required clearances around the device: 50 mm upward, 20 mm forward, 20 mm at the side, 10 mm downward, and 0 mm backward — these are the minimum air gaps for heat dissipation and arc-fault venting at the rated current.
