The 3RA2120-4DA27-0AP0: The operating temperature range is -20 to +60 °C, with storage and transport tolerance from -50 to +80 °C. Temperature compensation is active across the full operating band.
AC-3 motor duty and trip class
The maximum AC-3 operating voltage is 690 V.
Panel integration — size S0, DIN rail mount
Size S0 load feeder, 45 mm wide, 97 mm deep, 193 mm tall. Mounts vertically on 35 mm DIN rail using the screw-and-snap-on method; the fastening design also accepts screw mounting for backplate installations. Clearance requirements: 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side, 0 mm backwards. These are the minimum air gaps for heat dissipation and cable entry — respect them in the enclosure layout. Main circuit connections use screw-type terminals — no special tooling needed, but torque to the manufacturer specification during commissioning.
Supplied components — contactor and link module
This starter ships with the 3RT2027-1AP00 contactor and the 3RA2921-1AA00 link module pre-assembled. The contactor is the switching element; the link module integrates the overload relay and wiring interface into one package. The supplied contactor carries the same AC-3 rating as the assembled starter — 25 A at 400 V — so the combination is matched for motor starting duty without derating.
