For Sale 6000 Amp 480v Switchgear 3PH 4W Siemens Switch Board WBreakers. good condition and ready to use, This unit is a heavy-duty industrial grade electrical distribution system typically used in large manufacturing facilities, data centers, hospitals, and large commercial complexes.
6000 Amp 480v Switchgear 3PH 4W Siemens Switch Board WBreakers Specifications & Configurations
- Siemens SB Front-Connected Switchboards (UL 891): These systems support up to a 6000A main bus rating. They feature a compact layout that can be mounted directly against a wall because all terminations are accessible from the front, eliminating the need for rear clearance.Â
- Siemens Type WL Metal-Enclosed Switchgear (UL 1558): Engineered for maximum reliability with robust channel-shaped bussing. It offers up to a 6000A maximum horizontal and vertical bus system designed for high-fault environments with advanced air-flow cooling.

Core Components & Features
- Circuit Breakers: Systems of this scale use Siemens WL or newer 3WA series power circuit breakers. Breakers can be configured for manual or electrical operation and equipped with advanced electronic trip units (LSIG) providing integrated ground fault protection.Â
- Bussing Materials: Available with tin-plated aluminum, silver-plated copper, or tin-plated copper bus bars engineered for density or temperature ratings.Â
- Neutral Isolation: In 3-phase, 4-wire setups with multiple incoming power sources, Siemens 4-pole WL breakers are often specified to isolate the neutral and prevent nuisance ground fault tripping.Â
- Smart Monitoring: Typically integrated with Siemens ACCESS power monitoring on mains and branch breakers to manage real-time power quality and energy consumption
