Product Overview
GCS low-voltage withdrawable switchgear is used for power distribution, motor centralized control, and reactive power compensation. It is commonly used for industrial power distribution and motor centralized control, with the final selection based on rated data, drawings, and site conditions.
panel builders, EPC companies, electrical contractors, industrial users, and overseas distributors can request configuration review for withdrawable low-voltage switchgear for motor centralized control and reactive compensation. Please send main circuit scheme, busbar current, feeder arrangement, drawer or fixed cabinet structure, protection, and installation layout, quantity, destination, and any project standard requirements for quotation.
Model and Meaning
- GCS: enclosed draw-out switchgear system
- Confirm the main-circuit scheme number and auxiliary-circuit scheme number
