Product details

Motor power across the voltage range

The 3RA2316-8XB37-1CK2: At 480 V the rated current is 7.6 A; at 600 V it's 9 A, so the same assembly handles a range of motor frame sizes depending on your supply voltage.

Panel fit and mounting flexibility

Size S00 frame measures 90 mm wide, 68 mm high, 130 mm deep — compact enough for dense panel layouts, and it mounts on 35 mm DIN rail with either screw or snap-on fastening.

Wiring and terminal details

Both the magnet coil and main current circuit use screw-type terminals — no special tooling needed for field replacement or retrofit.
