The
Terasaki Key Interlock is engineered for secure and safe operation of electrical switchgear. By controlling the insertion and removal of keys, it ensures that breakers cannot be operated unless the system is in a safe condition, preventing accidents caused by human error.
This interlock system is compatible with air circuit breakers (ACB) and molded case circuit breakers (MCCB), providing flexible integration for industrial, commercial, and utility applications. Its robust mechanical design guarantees long-term reliability, even under heavy-duty usage.
Widely used in power distribution boards, industrial switchgear, and control panels, the Terasaki Key Interlock helps implement lockout-tagout (LOTO) procedures, providing both operational safety and compliance with electrical safety standards.
