The Omron J7KNA120124D is a 3-pole contactor from the J7KNA series, rated for 12 A AC switching current and 5.5 kW switching power at 690 V AC. With a 3NO main contact configuration and a 1NC auxiliary contact built in, it handles motor starting and isolation in a single package. The 10 HP rating (per) lines up with small three-phase motors on conveyors, pumps, or compressors.
Mounts on DIN rail or directly with screws (both supported per), giving panel builders flexibility in retrofit or new-build enclosures. Screw terminals accept standard ferruled or solid conductors — no special tooling required. The 2 A DC switching rating at 220 V DC covers smaller DC loads like brake coils or indicator circuits, though the primary duty is AC motor switching.
