Square D 9422TCF33 Industrial Control Relay Module

Square D 9422TCF33 is a three-pole fusible disconnect switch in Schneider Electric's Square D line, designed to provide safe isolation for three-phase circuits in industrial control panels and equipment enclosures. Rated for 30 A at up to 600 V AC, it accepts Class H, J, K, and R fuseholders, allowing protective fusing to match the load and duty cycle. This flange-mounted device is part of the 9422 family and is intended for control-panel installations where maintenance or emergency disconnection is required, enabling clear de-energization of all three phases with a single device. With its robust construction and standard 3‑pole configuration, the 9422TCF33 is suitable for motor circuits and power-distribution points in industrial environments, including machine control, conveyors, and processing lines. The model supports up to 20 HP motor loads at 600 V, aligning the switch’s current rating with practical motor starting and running requirements while keeping voltage protection consistent across phases.
