Square D Q2P3125 Three-Phase Industrial Contactor

Square D Q2P3125 Three-Phase Industrial Contactor is a 125 A, 240 V, 3-pole device in the Square D Q2P family, designed to remotely switch three‑phase motor and heavy-load circuits in industrial control panels. The model number encodes a 3-pole, 125 A configuration, while the 10K marking indicates a high fault-current capability that supports reliable operation in typical industrial electrical environments. This contactor switches loads at 240 VAC, making it suitable for controlling motors, pumps, fans, and other three‑phase equipment in manufacturing, processing, and HVAC applications. As part of Square D's portfolio, the Q2P line is designed to be integrated into motor-control schemes alongside protective relays and control circuits, providing a straightforward means to energize and de-energize motor circuits from a centralized control location. In motor-control applications, it is commonly paired with overload relays and auxiliary contacts to tailor protective and signaling functions to the installation requirements. The Q2P3125’s robust construction supports frequent switching duties typical of industrial environments, delivering reliable operation under load conditions and contributing to efficient, safe equipment control in industrial facilities.
