What this reversing contactor is — and why it saves panel time
The LC2K09015P7 is a TeSys K reversing contactor — a 3-pole unit rated 9 A in AC-3/AC-3e duty at 440 V, with a 230 V AC coil and one NC auxiliary contact. It comes preassembled with the reversing power busbar, which means it lands on the DIN rail as a single mechanical and electrical unit rather than two separate contactors you wire together on site. For a panel builder or field tech swapping a failed reversing starter, that cuts install time to minutes.
The AC-3 and AC-3e rating at 440 V is the one that matters for motor starting — 9 A covers a 3 kW induction motor on a 400 V line. AC-4 covers plugging and inching duty, so it handles reversing applications where the motor is switched while still spinning. The 230 V AC coil is standard for North American and European control voltages — pulls in reliably down to about 0.85 x nominal. Solder pin terminals suit a PCB or a pre-wired control board, not field wiring; if you're landing field cables, you'll want the screw-clamp variant in the same TeSys K family.
Where it goes — the deployment context
This is a DIN-rail reversing contactor sized for a panel — the 57 mm depth and 90 mm width fit a standard 35 mm rail with room for a motor circuit breaker and overload relay alongside it. The preassembled reversing busbar means the mechanical interlock and power cross-wiring are already done; you just land the line and load wires, wire the coil, and connect the NC aux into your safety or feedback circuit. It's a control contactor — used for switching motor loads in conveyors, pumps, fans, and compressors where forward/reverse operation is needed. The AC-4 rating confirms it's suited for frequent reversals, not just occasional direction changes.
