Product overview A four pole electrical switching device rated for AC 400V, designed for reliable control of multi phase power circuits. The 4P configuration allows simultaneous switching of three phase lines and the neutral line, simplifying wiring and ensuring consistent contact across all conductors. Key benefits Accurate multi pole switching: Switches all four conductors at once to maintain phase alignment and prevent unwanted backfeed between lines. Rated for AC 400V: Built for standard three phase systems up to 400 volts, making it suitable for common industrial and commercial installations. Simplifies installation: Single device replaces multiple single pole units, reducing wiring complexity and panel space. Durable design: Constructed for continuous electrical service and repeated operation in typical electrical distribution environments. Versatile compatibility: Suitable where neutral switching is required or preferred, and where coordinated control of all phases is needed. Important attributes Function: Four pole switching for multi conductor AC circuits. Compatibility: Designed for three phase AC systems with neutral, rated at AC 400V. Size and rating: Specified rating AC 400V ensures compatibility with standard distribution voltages. Performance: Enables synchronized switching of phase and neutral conductors for consistent circuit behavior. Typical applications Distribution panels in factories and workshops where coordinated control of three phase supply and neutral is required. Motor control centers and equipment starters that need simultaneous isolation of all conductors. Commercial building electrical rooms for switching or isolating incoming three phase service including the neutral conductor. Why choose this product Choose a single 4P device rated for AC 400V when you need clear, coordinated control of multi conductor AC circuits, simplified panel wiring, and reliable operation in standard three phase installations.
