Shunt for splitter (current transformer CT, potential transformer PT) 'KBY-□'
KBY-□
Shunt used for direct current! Please use it first. Instruments for distribution boards, control panels, sub-distribution boards, and panels.
KBY-□ is our company's shunt. A shunt is used to measure the current in a direct current circuit. When the current in the circuit exceeds the rated value of the ammeter, a parallel circuit is created with the ammeter to divert the current for measurement. The circuit (resistor) that diverts the current in this way is called a shunt. The rated current display value of the shunt indicates the maximum current that can be measured, while the rated voltage drop value refers to the voltage drop between the output terminals when the maximum current flows through the shunt. This varies depending on the specifications of the measuring instrument, primarily being 50 mV or 60 mV. The grade of the shunt is classified into 0.5% and 1.0% based on the allowable limit after passing 80% of the rated current for 15 minutes.

Company information
Our company was founded in 1979 and has grown from producing early analog (needle-type) instruments to digital instruments, as well as products that allow for the observation of electrical data via wireless and the internet. This development reflects the strong commitment of our employees to walk alongside our customers. Additionally, we are making proactive investments in technology development at our affiliated research institute and are thoroughly operating our business processes with a customer-centric approach. We are dedicated to meeting the diverse needs of our customers through more differentiated services. In our case, we have become well-known in South Korea for our measuring instruments (analog, digital meters, and CT, VT). We have been exporting to Japanese companies for over a decade, and we have registered with Ipros to introduce our products to more Japanese customers. In 2022, we registered as a corporation in Tokyo and have since relocated our corporate office to Osaka under the name "LIGHTSTAR JAPAN." We also have Japanese staff on-site, and we look forward to serving you.
