Product description Compact 4pole unit with a 100 ampere rating designed for use in multiphase electrical distribution systems. Clear, applicationfocused specifications make selection and installation straightforward. Key benefits Fourpole configuration allows simultaneous switching or protection of threephase lines plus neutral, simplifying wiring and ensuring coordinated operation. 100A rating provides capacity for circuits and equipment that require up to 100 amperes of continuous service, reducing the need for parallel feeds. Spaceefficient design integrates multiple poles into a single device, saving panel space and reducing installation complexity. Clear sizing and function reduce selection errors and speed up installation and maintenance decisions. Function and compatibility Function: multipole switching or protection for threephase systems with a neutral conductor. Compatibility: intended for electrical panels and distribution systems that accept 4pole components rated for 100A. Suitable where coordinated switching of all conductors is required. Size: 100A rating defines the current capacity and is the primary sizing parameter for circuit selection. Performance and construction Rated for continuous loads up to 100 amperes, making it suitable for mediumload distribution circuits. Designed for reliable operation in standard electrical distribution environments. Streamlined form factor simplifies integration into panel layouts where a fourpole solution is preferred. Practical use scenarios Commercial distribution: central protection or switching for a small commercial threephase main that requires a neutral connection. Equipment protection: coordinated switching of a threephase motor circuit and neutral conductor for mediumpower motors or HVAC units that draw up to 100A. Backup and transfer: use as a coordinated fourpole switching element in systems that require simultaneous disconnection of all phase conductors and neutral during transfers or maintenance. Why choose this specification Choosing a 4pole, 100A component ensures that all phase conductors and neutral are handled together, improving system coordination and simplifying wiring practices. The clear 100A rating aids engineers and electricians in matching the component to load requirements without guesswork. Ordering note Verify panel compatibility and mounting requirements against the 4pole form factor and the 100A current rating before ordering or installation.
