4 Pole 100A Circuit Breaker Automatic Transfer Switch for Three Phase Generator Panel

4Pole 100A Circuit Breaker Overview A 4pole, 100 amp protective device designed for threephase electrical systems. Provides centralized circuit interruption for a single multiconductor load or commontrip protection across four poles. Compact and easy to install where a 4pole unit is required. Key benefits Clear, consolidated protection for threephase circuits plus neutral using a single 4pole unit. Supports loads rated up to 100 amps for reliable current handling in distribution panels and equipment feeders. Simplifies wiring and reduces panel space compared to separate singlepole breakers by combining four poles in one device. Commontrip operation ensures simultaneous disconnection of all poles for coordinated fault response. Important attributes Poles: 4P (four pole) Rating: 100A (ampere rating) Function: Combined fourpole circuit interruption for threephase circuits with neutral Compatibility: Fits panels and switchgear that accept 4pole, 100A breakers or modules Performance: Designed for continuous operation at the rated current and coordinated disconnection of all poles Practical applications Commercial distribution panels where a single breaker must interrupt all three phases and neutral for a subfeed or branch circuit. Motor control and starter circuits requiring common disconnection of a threephase motor and its neutral conductor. Generator transfer and distribution panels that need a single device to isolate multiconductor outputs. Why choose this configuration By combining four poles into one 100A unit, this product streamlines panel layouts and ensures coordinated interruption of multiconductor loads. It is suitable for electricians and facility managers who need a compact, straightforward solution for threephase protection without handling multiple separate breakers. Installation notes Verify panel compatibility for 4pole devices and confirm proper bus connection and mounting space. Match the 100A rating to conductor size and load requirements according to applicable electrical practices and codes.
