Product Overview
Eaton’s Power Defense™ PDC5 series molded case circuit breakers (630–1600A) are a globally certified platform designed to safely distribute, switch, and control electrical energy in industrial, building, and machinery applications. Featuring Power Xpert Release (PXR) electronic trip units with LCD display, built-in communications, and advanced metering, the PDC5 delivers intelligent, reliable protection for modern power distribution systems.
Product Features
● PXR Electronic Trip Units：PXR20 (current metering) and PXR25 (power metering) with standard LCD display, integrated Modbus, and extended setting ranges.
● Arcflash Reduction Maintenance System (ARMS)：Uses unique low-latency analog circuit to interrupt faults faster than instantaneous protection, significantly reducing arc flash incident energy to protect operators.
● Zone Selective Interlocking (ZSI)：Achieves selective coordination by simply wiring breakers in series with cables, no additional modules needed; minimizes fault clearance time and system impact.
● Multiple Breaking Ratings：K: 50kA, P: 85kA, H: 100kA at 380–415V; available in 3P and 4P configurations, plus disconnecting switch variants.
● Comprehensive Communication：Built-in Modbus (standard on PXR25) plus optional external modules (Profibus-DP, Modbus, Ethernet) for seamless SCADA/network integration.
● Rich Accessories：Motor operator, shunt/closing releases, undervoltage release, auxiliary contacts, operation counter, door escutcheons, and communication modules.
● Flexible Protection Types：LSI, LSIR, LSIG, LSIGR trip unit options with three programmable general-purpose relays for customized signaling.
Product Advantages
● Global Certification：CE/CCC certified for worldwide deployment, meeting diverse regional regulatory requirements.
● Enhanced Safety：ARMS + ZSI combination minimizes arc flash energy and isolates faults at the nearest breaker, protecting both personnel and downstream equipment.
● Smart Energy Management：PXR25 power metering delivers real-time energy data (kW, kVA, kWh, power factor) without additional meters, enabling facility energy optimization.
● Simplified Engineering：PXPM software enables remote configuration, waveform capture, and trip testing via USB, reducing commissioning time and simplifying field maintenance.
● Wide Application Range：630A to 1600A with breaking capacities up to 100kA covers diverse distribution needs in a single platform.
● Robust Construction：Operating temperature -25°C to 70°C, IP20, pollution level III, rated impulse withstand voltage 8kV — built for demanding industrial environments.
Usage Scenarios
● Industrial Power Distribution：Main and sub-distribution boards in manufacturing plants, processing facilities, and heavy industry.
● Commercial Buildings：Electrical distribution in high-rise buildings, data centers, and large commercial complexes.
● Machinery Manufacturing：Power protection and control for industrial machinery and production lines.
● Infrastructure Projects：Power distribution in transportation hubs, airports, and public infrastructure requiring high reliability and arc flash safety.
● Harsh Environments：Applications with demanding temperature, dust, or washdown conditions where robust protection and global certification are essential.
