Low Voltage Switchboard

Main switchboards are not only recognized as useful means of power source protection but also highlighted as central means for controlling power.
Specializing in the manufacture of marine electrical equipment, KTE has so far developed various products adapted for the users’ needs on the basis of our long year expertise and the latest technology.
We would like to introduce our trusted marine use switchboards, which meet the rules and regulations of the classification societies of various countries such as ABS, BV, CCS, DNV, GL, LR, NK and KR.

Long life span and reliability

KTE marine switchboards are adaptable to all possible ship conditions as the most reliable components have been chosen on the basis of over 30 year accumulated experiences.
Excellent anti-corrosive coating, baked melamine finish and orderly device arrangement make the switchboards more reliable.

Rigid construction and safety

The switchboards are sufficiently drip-proof and durable against vibration, moisture, heat and shock. KTE has also acquired Type Approval Certificates from Germanischer Lloyd for switchboards.
From design stage of the products, KTE thoroughly reflects all the safety rules and regulations of international standards and classification societies to the switchboards.

Best suited arrangement

Almost all type of marine switchboards have already been delivered in large quantities. Which means that system satisfies various user requirements and are ready for immediate applications.

Rules and regulations

KTE has acquired Type Approval Certificate for Low Voltage Switchgear system from Germanischer Lloyd.
KTE maritime switchboards also meet the rules and regulations of the classification societies of various countries including ABS, BV, CCS, DNV, LR, GL, RINA, NK, KR.
