Schneider Electric 8430-V3-460 Load Detector

Schneider Electric's Square D 8430-V3460 Load Detector is a Class 8430, Type V motor load detector designed for three‑phase 460 V systems. It monitors motor load by measuring input voltage, current, and power factor to calculate true motor power, while compensating for intrinsic motor losses to help protect inductive motors from overload and inefficiency. The Type V family provides maximum and minimum trip points, enabling protective actions based on defined load thresholds, and is commonly paired with motor control relays and contactors in industrial panels. The device includes motor line voltage terminals L1, L2, L3 for direct connection to the 460 V, three‑phase power supply and the connected motor, aligning with Square D’s legacy motor protection solutions. The 8430‑V3460 variant is frequently encountered in legacy installations for monitoring motor load on 460 V systems, making it a reference choice for applications such as conveyors, pumps, and fans in manufacturing and processing environments.
