Features and Applications of CSP Oil-Immersed Circuit Breakers
CSP low-voltage oil-immersed circuit breakers use an oil-insulated and arc-quenching design that effectively prevents contact damage and extends service life.
They are especially suitable for single-phase distribution transformers up to 167KVA, commonly used in rural power networks, utility pole-mounted transformer systems, and small industrial power distribution setups.
Compared to air-type breakers, CSP oil-immersed breakers offer better heat dissipation, higher protection sensitivity, and improved environmental adaptability.
