The TERASAKI MS 3P Mechanical Interlock is an essential MCCB accessory used in applications where two power sources—such as mains and generator—must never be connected at the same time. This mechanical interlock physically prevents one breaker from closing while the other is in the ON position, ensuring safe and reliable changeover operation.
Designed specifically for TERASAKI TEMBREAK MCCBs, the MS 3P interlock offers smooth mechanical operation, high durability, and long service life. Its rugged construction makes it suitable for industrial panels, commercial power systems, and critical infrastructure where electrical safety is paramount.
Manufactured to TERASAKI’s strict quality standards, this mechanical interlock eliminates the risk of back-feeding and short circuits during source changeover. Choosing the TERASAKI MS 3P Mechanical Interlock ensures maximum safety, compatibility, and peace of mind.
