Automatic Transfer Switch 4P 100A for Three Phase with Coordinated FourPole Protection

Compact 4P 100A electrical protection device designed for use in three phase systems with neutral. The four pole, 100 amp rating provides coordinated control and overcurrent protection across all phases and the neutral conductor, simplifying panel layout and wiring. Key benefits Singledevice protection for three phase plus neutral: protects all conductors together for coordinated response and easier installation. Clear rating and sizing: 100 amp per pole rating makes selection straightforward for feeders and branch circuits up to 100 A. Space efficient: four pole configuration reduces the number of separate breakers needed and saves panel space. Consistent switching: simultaneous disconnection of all poles reduces the risk of leaving a conductor energized when servicing circuits. Simplified inventory and maintenance: one consistent unit for multipole applications reduces complexity. Important attributes Function: overcurrent protection and simultaneous isolation for four conductors in three phase systems with neutral. Size: 4P 100A, four poles, 100 amp rated current per pole. Compatibility: intended for use in standard three phase distribution panels, switchboards, and electrical enclosures where a four pole 100 A protection device is required. Performance: designed to provide reliable switching and tripping for circuits up to the specified 100 A rating. Construction: built for electrical distribution use with a compact footprint that fits common panel layouts. Use scenarios Commercial building main feeder: use as the main protection device for a small commercial three phase distribution board feeding lighting and power subcircuits. Backup generator output protection: integrate into a transfer or distribution panel to isolate and protect the generator supply and neutral when transferring loads. HVAC and equipment feeders: protect three phase HVAC units or industrial equipment feeders where a single device controlling all phases and neutral is required. Why choose this unit Straightforward specification with a clear 4P 100A designation for quick selection. Reduces wiring and space compared to multiple singlepole devices. Provides coordinated multipole isolation for safer maintenance and operation. Specification summary Size: 4P 100A For applications requiring a four pole device rated at 100 A, this unit delivers a compact, practical solution for three phase distribution and feeder protection.
