The
Terasaki Auxiliary CT for Earth Fault (EF) Protection is an essential protection accessory used in conjunction with Terasaki circuit breakers and protection relays. It accurately senses residual or earth fault currents, enabling fast and reliable tripping during ground fault conditions.
This auxiliary CT plays a critical role in preventing equipment damage, fire hazards, and electrical shock risks by detecting leakage currents that are not measurable by standard phase CTs. Designed for seamless integration with Terasaki protection systems, it delivers stable performance and high accuracy even in demanding industrial environments.
Manufactured using high-quality insulating and magnetic materials, the Terasaki Aux CT ensures long service life and dependable operation. It is widely used in ACBs, MCCBs, and advanced protection panels where enhanced earth fault protection is required.
