Overview

Switchgear Solutions by NLC BMC

Switchgear is the backbone of any electrical distribution system, responsible for controlling, protecting, and isolating electrical equipment. NLC's BMC division designs, manufactures, and installs high-quality switchgear assemblies for low-voltage (LV) and medium-voltage (MV) applications across Saudi Arabia.

Every switchgear solution is built to IEC 61439 standards, assembled in our modern manufacturing facility, and subjected to rigorous factory acceptance testing before delivery to site.

Switchgear Types

Main Distribution Board (MDB)

Low Voltage (LV) Switchgear

Main distribution boards (MDB) and synchronization (sync) panels for voltages up to 1,000V AC.

Up to 1kV
Medium Voltage (MV) Switchgear

Medium Voltage (MV) Switchgear

Metal-clad and metal-enclosed MV switchgear for primary distribution networks, substations, and ring main units (RMU).

1kV – 36kV
Motor Control Centers (MCC)

Motor Control Centers (MCC)

Integrated motor starter assemblies for pumping, HVAC, and process equipment, with DOL, star-delta, and VFD options.

Industrial
Busbar Trunking Systems

Busbar Trunking Systems

Compact busbar trunking for distribution in high-rise buildings, data centers, and industrial facilities, with tap-off units for flexible load connections.

High-Rise & Industrial
