Frequently Asked Questions

What is the application of KYN27-12 switchgear?

It is primarily used for receiving and distributing power in 3.6-12kV three-phase AC 50Hz electrical networks, providing control, protection, and monitoring.

What is the protection level of the enclosure?

The enclosure provides a protection degree of IP4X, while the protection between compartments is IP2X, ensuring safety during operation.

Does this model support different current ratings?

Yes, the main busbar rated current ranges from 630A up to 4000A, allowing for flexible configuration based on network requirements.

What are the standard dimensions?

The standard height is 2250mm, with various widths (650/800/1000mm) and depths (1400/1600/1700mm) available to fit different installation spaces.

Is the switchgear compliant with international standards?

Absolutely. It complies with the latest IEC 62271-1, IEC 62271-100, and IEC 62271-200 standards for high-voltage switchgear.

What does LSC2B signify?

LSC2B (Loss of Service Continuity) means that other compartments can remain energized and functional while one high-voltage compartment is being serviced.
