Four-pole design with 100% neutral protection provides comprehensive circuit coverage, reducing neutral fault risk. This translates to improved safety margins and fewer mis-trips in multi-wire panels. In practice, it fits motor control centers and industrial panels where full neutral protection is essential for reliable operation. 800 A amperage rating paired with a 50kA/50kA interrupt capability delivers robust protection for high-current feeders. This limits fault energy, protects conductors, and supports longer equipment life. Applications include large manufacturing lines and data-center power distribution where high fault currents are possible. Thermal magnetic tripping with adjustable thermal and adjustable magnetic settings allows precise coordination with downstream devices. This reduces nuisance trips and improves selective coordination, lowering maintenance costs. Applications include feeders to motors and drives where protection must align with upstream breakers. Screw terminals with metric tapped conductors enable secure, field-friendly wiring and consistent torque. This facilitates faster installation, fewer termination failures, and easier panel automation integration. Applications include panel builders and OEMs assembling Power Defense MCCBs into compact switchgear. Part of the Power Defense family, this MCCB offers OEM compatibility and streamlined spares across service fleets. This simplifies procurement and reduces downtime through standardization and interoperability. Retrofit projects and new builds in industrial plants benefit from consistent protection across rooms and lines.
