Key Advantages
IEC 61439 & GB/T 7251 Compliant: Fully type-tested enclosure and busbar design ensuring strict compliance with international safety and performance standards.
Zero-Downtime Maintenance: Independent withdrawable drawer design allows circuit inspection, maintenance, or replacement without shutting down the main busbar system.
Brand-Flexible Component Integration: Compatible with top global electrical brands (Schneider Electric, ABB, Siemens) or reliable OEM brands based on your project budget and specifications.
Triple Safety Interlocking: Mechanical and electrical interlocking guarantees drawer operation strictly within "Connected / Test / Isolated / Removed" positions, preventing human operating errors.
Robust Short-Circuit Capacity: Designed to withstand short-time withstand currents up to 100kA (1s), tailored for high-demand industrial power distribution networks.
Flexible Drawer Module Functions
Each withdrawable unit functions as an independent operational cell, integrating:
Circuit Protection
Air Circuit Breakers (ACB) / Molded Case Circuit Breakers (MCCB)
Motor Control
Contactors, Thermal Overload Relays, Soft Starters, VFDs
mart Monitoring
SDigital Power Meters, Modbus/RS485 Communication, PLC Integration
