Application
Low Voltage Withdrawable Switchgear systems like GCK, GCS, and MNS (also known as SYN) are essential components in low-voltage power distribution and motor control applications. It is suitable for transformer station, electric power plant, petrochemical industry, metallurgical steel rolling ,traffic energy,light and textile industry ,and residence community, high building ..etc. As electric power energy conversation ,distribution & controlling for power distribution equipments of AC 50/60Hz rated service voltage 690V or lesWithdrawable switchgear means that individual units or modules can be removed or replaced without disrupting the entire system, allowing for flexibility and ease of maintenance. GCK, GCS, and MNS systems are highly customizable, allowing for both power distribution (for loads) and motor control (for machinery).
GCK (General Construction Kit):
The GCK type of low-voltage switchgear is designed for power distribution and motor control in medium-scale applications. Known for its modular construction, it allows for easy expansion and configuration adjustments.
GCK switchgear typically supports motor control centers (MCC), power distribution, and lighting control in facilities.
It’s often used for applications that need moderate flexibility and control capabilities, such as factories, water treatment plants, and small-to-medium industrial facilities.
GCS (General Control Switchgear):
The GCS model is designed with more advanced flexibility and customization options, commonly used in complex industrial settings requiring high reliability and flexibility.
GCS systems are widely used in motor control, power distribution, and reactive power compensation applications. Their modular design allows for easy reconfiguration, making them ideal for facilities with changing power demands.
The GCS type is often chosen for larger power distribution applications like manufacturing plants, chemical industries, and data centers.
MNS (Modular Network Switchgear) or SYN:
MNS, also referred to as SYN in certain markets, is an advanced modular low-voltage switchgear designed with high reliability, safety, and flexibility.
It uses a compact, space-saving design with modular, withdrawable units that offer ease of maintenance and expansion.
MNS is often the choice for critical power applications due to its high level of safety features, including arc fault protection, and is widely used in power-intensive industries like petrochemical, mining, and renewable energy sectors.
