Busbar current transformer (CT) "KBM-□□" suitable for air-insulated circuit breakers.
KBM-□□
Any type of circuit breaker for ugly bars can be matched. It is a product with good performance and price. Instruments for distribution boards, control panels, distribution panels, and panels.
KBM is our busbar type CT, particularly suitable for air circuit breakers (ACB). The range of primary current is very wide, from 100 to 12,000, allowing for versatile use. The KBM series has diversified the size of the CT to match the size of the circuit breaker. It offers more varieties than busbar CTs for circuit breakers, making it a versatile product that can be used in various situations. By installing three units, it can also be used like a three-phase CT. For the KBM-03 and KBM-25, production will continue until this year, and it is scheduled to be discontinued next year. However, new products KBM-13 and KBM-16 have been released, so the total number of varieties remains at nine. For inquiries, please contact "lightstar_1979@yahoo.co.jp".
