Metal Clad Switchgear

The UL/ANSI rated MCSG is designed to comply with IEEE standards. Available in 5, 15, 27, and 38 kV ratings, the platform supports high interrupting capacity and continuous current performance for medium-voltage power distribution applications.

Rated Voltage: 4.76/15/27/38 kV
Rated Current: 1200/2000/3000/4000 A
Short-Time Current: 25/31.5/40/50 kA

Key Features

Modular Structure

LS ELECTRIC MCSG features a modular, stackable structure designed for efficient assembly.

Maintenance-Friendly Design

Cable connections and current transformers can be accessed from the front of the MCSG. This design enables easy maintenance, reduces required installation space, and provides a safe working environment.

Safety

Designed to disperse arc energy in the event of an internal arc, helping protect surrounding equipment.

Seismic Design

The MCSG is manufactured and supplied with appropriate seismic performance through seismic compliance analysis and a robust structural design approach.
