What this product is

What this product is

This unit serves as the primary AC ingress power distribution interface in large Huawei telecom power cabinets, distributing utility or generator AC power directly to the rectifier subrack backplane while providing over-current isolation and energy sampling.

What problem it solves

Eliminates complex external cabling, prevents busbar overheating through low-impedance gold-plated contacts, and enables hot-swap maintenance without powering down the entire telecom power cabinet.

Who and where it is for

Engineered for telecom switching centers, 5G core network facilities, modular IDC energy rooms, and maintenance/expansion of Huawei TP482000B and ETP48400 power systems.

Core advantages

  • 100A High-Current Capacity: Supports 200~240V / 346~415VAC 3-phase and single-phase AC input, reliably carrying continuous loads up to 100A.
  • Heavy-Duty Blind-Mate Connectors: Features gold-plated low-resistance busbar contact fingers and alignment guide rails for secure, low-loss power transfer.
  • Comprehensive Electrical Protection: Integrates circuit breakers and overload isolation to safeguard downstream rectifier modules from grid surges.
  • Native Huawei Architecture Integration: Seamless mechanical and electrical fit for Huawei high-capacity power cabinet backplanes with true plug-and-play operation.
