It's a 3-pole (3 NO main poles) contactor pair in one package, rated for AC-3 duty at 6 A up to 440 V and AC-4 duty, meaning it's sized for small reversing motor loads like conveyors, hoists, or valve actuators where direction change is part of the cycle. The 115 V AC coil is standard for North American control circuits.
Integration notes — panel fit and wiring
The preassembled reversing busbar saves wiring time but locks the contactor pair into a fixed mechanical interlock; there's no field adjustment for contactor spacing. The 115 V AC coil draws its rated inrush and hold current from the control transformer; verify the transformer VA rating can handle the inrush of two contactor coils energising simultaneously during a reversing transition.
Mechanical and environmental robustness
Rated for shock and vibration per IEC 60068-2-27 and IEC 60068-2-6: the contactor holds closed under 10 Gn on Y and Z axes, 4 Gn vibration closed. That's sufficient for most industrial machinery but not for extreme mobile or marine applications where higher shock profiles apply. Flame retardance meets UL 94 V1 and NF F 16-101/102, which is standard for rail and building infrastructure compliance.
