WEG WPDKB Low Voltage Power Distribution Panel

The WEG WPDKB Low Voltage Power Distribution Panel is a factory-assembled, type-tested low voltage switchboard designed for main incoming, bus sectionalising, and outgoing feeder distribution duties in industrial facilities, commercial complexes, and infrastructure projects across Saudi Arabia. Constructed to IEC 61439-2 Part 2 type-tested switchboard standards, the WPDKB-3200A variant handles busbar ratings up to 3,200 A continuous at 400 V three-phase, 50 Hz, with prospective short-circuit current withstand up to 100 kA RMS for 1 second. The enclosure is IP31 as standard, with IP43 and IP54 options for locations subject to water spray and dust ingress, addressing the range of installation environments from clean indoor switchrooms to semi-outdoor utility buildings in Saudi Arabia's coastal and desert industrial zones.

The WPDKB panel is built on a modular steel frame system with fully withdrawable circuit breaker modules for all incomer and feeder positions, allowing circuit replacement or maintenance under live busbar conditions without disrupting adjacent circuits — a feature that meets ARAMCO's brownfield maintenance requirements and NEC 2020 Article 408 requirements for switchboard accessibility. The busbar system uses electrolytic copper throughout with silver-plated joints, providing stable contact resistance over decades of operation in the Kingdom's fluctuating temperature environment. Protection devices are WEG BMDR series moulded case circuit breakers with Iridium electronic trip units for adjustable overcurrent and ground fault protection, providing selectivity coordination between main incomer and downstream feeders per IEC 60947-2 selectivity class.

Saudi Arabia's expanding industrial, commercial, and infrastructure sectors generate continuous demand for main distribution boards across the full spectrum of project types: NEOM Sindalah Island resort and marina facilities, King Salman Energy Park (SPARK) industrial buildings, ARAMCO offshore platform living quarters, and NWC regional water treatment plants all require main distribution switchboards that balance construction quality, delivery lead time, and total cost of ownership. The WPDKB's IEC 61439-2 type test certification — covering temperature rise, short-circuit withstand, dielectric, mechanical operation, protection, and earthing — provides the design authority confidence required for SEC authority approval drawings and ARAMCO/SABIC project documentation packages. The panel's compatibility with WEG's range of BMDR MCCBs, MDW MCBs, CWC contactors, and metering equipment from a single manufacturer simplifies procurement, spares management, and technical documentation.

Razz Middle East designs, manufactures (in partnership with WEG-authorised panel shops), supplies, and commissions WPDKB distribution panels for Saudi Arabia projects. We provide single-line diagrams, protection coordination studies, cable sizing schedules, and authority approval documentation packages in Arabic and English. Our panel manufacturing partners hold IEC 61439-2 type test certificates and SASO product registrations for the Saudi market. Delivery schedules are agreed at order stage, with standard boards typically delivered in 6–10 weeks from confirmed order.
