4P100A — Fourpole, 100 A electrical unit designed for threephase systems Key benefits Fourpole design with 100 A rating enables simultaneous switching and isolation of three phase conductors and neutral for safer, coordinated control. Clear size designation makes it easy to select and match to distribution panels and electrical assemblies that require a 4P100A component. Compact footprint and predictable performance simplify installation and system planning, reducing commissioning time. What this delivers Function: Provides coordinated switching and isolation for threephase power lines plus neutral, suitable where all poles must operate together. Compatibility: Intended for use in 3phase electrical systems that accept a 4P100A module. Fits most panel arrangements that accommodate fourpole, 100 A devices. Performance: Rated for continuous operation at 100 A per the 4P100A specification, supporting typical loads found in light industrial and commercial installations. Why customers choose this size Ensures neutral is switched together with phase conductors, preventing floating neutral conditions in threephase installations. Simplifies wiring and panel layout when a single, fourpole solution is required. Provides a predictable current capacity for selecting downstream components and protective devices. Typical applications Distribution panels for small commercial buildings where threephase equipment and neutral need common isolation. Motor control and feeder lines for pumps, compressors, and machinery that require coordinated disconnection of all poles. Backup power and generator transfer setups where neutral switching must be included in the transfer sequence. Installation notes Confirm panel space and mounting configuration match the 4P100A size before ordering. Coordinate upstream and downstream protective devices to the 100 A rating for proper system operation. This 4P100A size offers a straightforward, reliable option when a fourpole, 100 A solution is required for threephase electrical distribution and control.
