The Terasaki TB2C Mechanical Interlock is used in dual-source power systems where two MCCBs—such as utility and generator supplies—must never be ON at the same time. This mechanical interlock physically blocks one breaker from closing while the other is in the ON position, eliminating the risk of back-feeding and electrical faults.
Engineered for TERASAKI TEMBREAK MCCBs, the TB2C 3-pole mechanical interlock delivers smooth mechanical operation, high durability, and reliable performance in demanding environments. Its compact and rugged design makes it ideal for industrial panels, commercial buildings, and critical power installations.
Manufactured to TERASAKI’s strict Japanese quality standards, this interlock ensures maximum operational safety, compliance, and long service life. Choosing an original Terasaki TB2C Mechanical Interlock guarantees perfect compatibility and complete peace of mind.
