Terasaki circuit breakers have the advantages of high breaking capacity, fast tripping characteristics, good stability and reliability, and can adapt to various complex working environments. Terasaki marine circuit breaker series are designed and manufactured according to the special requirements of ship electrical systems, meeting the high safety and reliability requirements of ships for electrical equipment when sailing at sea. Terasaki marine circuit breakers have a variety of models, the following are some common models: - **E series**: such as [E125 NJ 3P PMC](https://www.cwlyautomation.com/product/6200.html "E125 NJ 3P PMC"), suitable for protection of overload, short circuit and other faults in ship power systems, with good breaking capacity and stability. - **S series**: including S100 GF 40A 3P, S250 NF and other models. S100 GF 40A 3P can be used for some circuit protection on ships with current requirements of about 40A; S250 NF is suitable for circuit occasions with larger current loads. - **X Series**: There are models such as XS630SE, XS630NJ, XH50NS, XM225NS, and XH225NS. XS630SE and XS630NJ are often used for circuit protection of ship main switchboards or important loads, and can withstand large short-circuit currents; XH50NS is suitable for ship circuits with a current of 50A; XM225NS and XH225NS can be used in ship power distribution systems with different load requirements. - **AR Series**: For example, AR 440 SB-R, AR 332 S-R, etc., are air circuit breakers with high breaking capacity, can work reliably in the complex electrical environment of ships, and are suitable for circuit protection of larger currents and higher voltages. - **TL Series**: For example, TL-100C, is a current-limiting non-fuse circuit breaker, suitable for electrical systems such as ship low-voltage main switchboards, provides protection against overload and short circuit in circuits, and has the characteristics of fast response speed and small size.
