The 3RA2110-1FA15-1AK6: This is a non-fused load feeder from the SIRIUS 3RA2 family, designed as a direct starter — meaning it combines a contactor and overload relay in one assembly for across-the-line motor starting. The size S00 frame keeps the width at 45 mm, fitting standard 35 mm DIN rail with screw or snap-on fastening, so it slots into a compact motor control center or panel without eating up rail space. The trip class is Class 10, which means it disconnects the motor within 10 seconds under locked-rotor conditions — standard for most general-purpose motor applications like pumps, fans, and conveyors where the starting time stays under that window. The supplied contactor is a 3RT2015-1AK61, and the link module 3RA1921-1DA00 handles the internal wiring between the contactor and the overload block, so the assembly arrives as one wired unit.
Electrical ceiling — AC-3 switching at 690 V and the power bands that matter
Rated maximum voltage is 690 V in AC-3 duty (switching motor loads), which covers 400 V, 480 V, 600 V, and 690 V industrial systems. The current draw at 480 V is 4.8 A; at 600 V it's 4.55 A — these numbers tell you the thermal limit is current-driven, not voltage-driven, so the load feeder's capacity is set by the motor full-load amps, not the line voltage. Type of assignment 1 means the starter coordinates with the upstream short-circuit protective device (typically a circuit-breaker or fuse) such that the contactor and overload relay survive a fault up to the rated conditional short-circuit current without welding or damage.
Panel fit and environmental limits — the dimensions that decide the layout
The unit measures 45 mm wide, 167.2 mm tall, and 97.1 mm deep — the depth is the dimension that matters most when the panel depth is tight, because 97.1 mm includes the contactor arc chamber and the overload relay body. Clearance requirements: 20 mm upward, 10 mm downward, 9 mm to the side, and 0 mm forward or backward — so you can butt it against the back panel or a busbar without extra spacing. Operating temperature range is -20 to +60 °C, storage and transport go from -50 to +80 °C. Degree of pollution 3 means it's rated for conductive pollution in industrial atmospheres (dust, moisture, chemical residue) — standard for factory-floor panels without filtered air. Mounting position is vertical only; horizontal mounting would alter the thermal trip curve of the overload relay.
Sourcing — current production, quoted to order
The supplied link module (3RA1921-1DA00) simplifies the control wiring between the contactor coil and the overload relay's NC contact, reducing panel wiring time.
