Product overview A threepole electrical protection device with a 125 ampere rating, supplied in the 3P configuration for threephase systems. Designed to provide reliable circuit interruption and easy integration into threephase distribution panels. Key benefits Clear function: Provides threepole protection for threephase circuits rated up to 125 amperes, simplifying wiring and protection in multiphase installations. Space efficient: The compact 3P form factor reduces panel footprint while keeping all three poles grouped for neat, organized installation. Compatibility: Suited for use in standard threephase distribution panels and equipment where a 125A threepole device is required. Ease of use: Grouped poles make wiring straightforward and reduce installation time compared with separate singlepole devices. Durable design: Built for repeated operation and stable performance under typical electrical load conditions. Features and important attributes Configuration: 3P (threepole) for coordinated protection of all three phases. Rating: 125A nominal current capacity; intended for circuits specified at this amperage. Function: Interrupts current on all three poles to isolate a threephase circuit when required. Size and fit: 125A rating corresponds to equipment sized for that current capacity; compact threepole arrangement helps fit into common electrical panels. Performance focus: Engineered to operate consistently at the specified rating for normal threephase distribution use. Practical applications and use scenarios Commercial electrical distribution: Protect threephase feeders in retail, office, or light commercial panels where a 125A threepole protective device is specified. Motor and equipment supply: Use as a protective supply disconnect for threephase motors or machinery that require coordinated isolation of all three phases at 125A. Subpanel or feeder protection: Install as the primary protection for a subpanel or feeder that serves smaller branch circuits supplied from a 125A threephase source. Installation notes Confirm system type and wiring: Use only in threephase systems and verify that a 125A rating matches the circuit design and upstream equipment. Match to panel space and mounting: Ensure the threepole device fits the intended panel or mounting arrangement before installation. Professional installation recommended: Installation and selection should follow applicable electrical codes and practices. This description reflects the 3P configuration and the 125A size specification. Use as a component in threephase electrical systems where a threepole 125 ampere device is required.
