Automatic Transfer Switch 4 Pole 125A 3 Phase Din Rail Mounted Electrical Selector for Dual Power

4pole, 125 amp electrical unit designed for multiconductor power distribution where simultaneous control or switching of four conductors is required. Key benefits Supports multiphase systems: 4pole (4P) configuration lets you switch or connect all three phases and the neutral together for coordinated operation. Clear capacity rating: sized at 125A to handle higher branch or feeder currents without overspecifying components. Simplifies wiring and maintenance: a single 4pole device reduces the need for separate singlepole units, cutting installation time and improving circuit organization. Consistent performance: specified nominal current provides predictable behavior when matched to panels and components rated for 125A. Important attributes Poles: 4P (fourpole) Size rating: 125A nominal current Function: multiconductor switching or connection for systems requiring coordinated control of four conductors Compatibility: intended for electrical panels, switchgear, and distribution systems designed for 4pole devices and 125A circuits Installation: fits standard 4pole mounting arrangements and wiring practices; use appropriate terminals and torque values as required by local codes Practical uses and applications Commercial distribution panels: centralize control of a small threephase service with neutral for lighting, HVAC, or general loads rated up to 125A per circuit. Motor and equipment feeders: provide coordinated switching for threephase motors plus neutral or for equipment that needs simultaneous disconnection of all conductors. Temporary or auxiliary power setups: use in portable distribution or generator output panels where a 4pole, 125A device is required to manage multiconductor connections. Notes for selection and installation Confirm downstream and upstream equipment ratings match the 125A nominal value and 4pole configuration. Ensure wiring, connectors, and protective devices in the circuit are rated for 125A continuous current and comply with applicable electrical codes. Follow standard installation procedures for torque, conductor preparation, and secure mounting to ensure reliable electrical connections. This 4P 125A unit is targeted for applications that require coordinated handling of four conductors at a defined 125 ampere rating. Select and install in accordance with system requirements and local regulations.
