What this SIRIUS direct starter covers
The 3RA2110-0FA15-1AP0 is a Siemens SIRIUS direct online starter in size S00, supplied as a pre-assembled unit with a 3RT2015-1AP01 contactor and a 3RA1921-1DA00 link module. The 120 kW figure at 400 V is the contactor's rated motor power, not the starter's continuous rating — the actual continuous current limit is 0.5 A, so this starter is sized for very small loads only.
Panel fit and clearance constraints
Clearance requirements are tight: 50 mm above, 20 mm forward, 10 mm below, 20 mm at the side, and zero clearance behind — plan the gland plate and wireway accordingly to avoid bending the outgoing cables too sharply.
Operating environment and compliance
Rated for operation from -20 to +60 °C, with storage and transport range of -50 to +80 °C — suitable for most indoor industrial panels but not for freezer or outdoor direct-sun applications without a heated enclosure.
