The PRM3 Series Molded Case Circuit Breakers (MCCBs) are engineered to deliver high-performance protection across a wide current range from 100A to 1600A. Designed for low-voltage power distribution systems, this series ensures dependable protection against overloads and short circuits in demanding environments.
With breaking capacities reaching up to 50kA at 415VAC, the PRM3 series is suitable for main incomers, feeder circuits, generator protection, and heavy industrial loads. The robust molded case construction enhances mechanical strength and electrical durability, ensuring long service life even under harsh operating conditions.
The thermal-magnetic trip mechanism provides accurate overload protection and instantaneous short-circuit interruption. For higher frame sizes, electronic trip unit options allow enhanced precision and adjustable protection settings, making the series adaptable to various system requirements.
Available in 3-pole and 4-pole configurations, the PRM3 MCCB series supports three-phase power systems commonly used in industrial and commercial facilities. The 800V insulation rating and 8kV impulse withstand capability ensure strong performance stability and protection reliability.
Typical Applications:
Main distribution panels
Industrial motor protection
Generator and transformer protection
Commercial building power systems
Heavy-duty manufacturing facilities
The PRM3 Series delivers the perfect balance between safety, performance, and cost-efficiency, making it a dependable solution for professional electrical installations.
