It carries three normally-open power poles and one normally-closed auxiliary contact, with a 240 V DC coil. The key rating for motor control is 12 A in AC-3 duty at ≤440 V, which means it handles a typical 5.5 kW induction motor on a 400 V three-phase line — the AC-3 category covers starting and plugging of squirrel-cage motors, so this is the number that decides fit for a conveyor, pump, or fan reversing circuit.
Integration Notes for Panel Builders
The preassembled reversing busbar means the two contactors are mechanically and electrically interlocked — no external wiring for the reversal logic. The 1 NC auxiliary (the '01' in the code) is built in; additional auxiliaries can be stacked on the front if needed, but verify compatibility with the K frame. The 240 V DC coil draws a holding current that depends on the coil resistance — typical for this frame is around 5-7 W holding. Ensure the DC supply can deliver the inrush (about 10x holding for 20-50 ms) without voltage sag. A free-wheeling diode across the coil is standard practice for DC suppression; polarity must be observed.
