The 3RA2225-1ED23-0AK6: It ships as a factory-assembled unit with the contactor (3RT2023-1AK60) and link module (3RA2921-1AA00) already matched, so there is no guesswork on coordination between the reversing contactor pair and the overload relay. The reversing function is built in — two contactors interlocked mechanically and electrically, ready for forward/reverse control of a motor.
Snap-on busbar mounting and panel clearances
Mounts by snapping directly onto 60 mm busbar systems — no DIN rail adapter needed, which saves a mounting step and keeps the feeder aligned with the busbar centerline. The mounting position is vertical only, so plan the busbar run accordingly. The envelope is 260 mm high × 90 mm wide × 155 mm deep. Clearance requirements around the unit: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the sides, and 0 mm backward — the back sits flush against the mounting surface. These are the minimum gaps for airflow and arc containment; crowding the top clearance will trap heat and reduce the continuous current capability.
Active production — sourcing the 3RA2225-1ED23-0AK6
The RoHS compliance date is March 1, 2017, so the unit meets the EU RoHS substance restrictions. No REACH or UL certification is explicitly listed in the spec record, but the SIRIUS 3RA2 series typically carries IEC and UL approvals — confirm the specific certification package with the order documentation if your panel requires UL listing.
