Circuit Breakers Division

Expanding our "reliability" further on a global scale

Circuit breakers protect human lives, buildings and properties against risks of electrical short circuit. Since our founding, TERASAKI has left competitors far behind in the field of circuit breakers and established a global name by acquiring accreditation under various international standards. We are pouring our technical and development strengths into markets in Europe, Southeast Asia, Middle and Near East, South America and elsewhere in which circuit breaker demand is expected to grow. We deliver products tailored to local needs. In Japan, we are developing new products for intranet systems based of the integration of information and communication technologies. TERASAKI is taking technology development beyond its limits to progress forward into a bright new future.

"Moulded case circuit breakers TemBreak2"

The TemBreak2 delivers top-class safety as a circuit breaker and is made from environment-friendly materials.

"Air circuit breakers TemPower2"

The TemPower2 is an air circuit breaker of the world’s smallest size. It protects any and all kinds of systems using a new OCR integrated with communication capabilities.

"Circuit breaker terminal temperature monitor "

The unit monitors the terminals of the circuit breakers installed in the power
distribution board, for overheat that would occur due to loose circuit breaker
connection bolt.

"DIN type circuit breakers"

TERASAKI produces EN (European Norm)-compliance DIN type breakers in Spain.

"Bus-coupled plug-in boards TemPlug"

The circuit breakers need only to be plugged into the main bus line. As branching bus bars are unnecessary, TemPlug offers solution for smaller distribution panels.

"Energy management system & software TemMonitor"

Hooked up with a device provided with energy monitoring function, the power monitoring system gets the energy consumption status displayed in graph and manages reports on a general computer.

"MCT(Multi-Cable Transits)"

The Multi-Cable Transit system is a proven fireproof, water and airtight method of passing cables from one compartment to another.

"Multi-Protection Relay TemTrip2"

TemTrip2 is a multi-protection overcurrent relay equipped with the directional ground fault trip,
the ratio differential trip and the reverse power trip function.
It shows various information including the phase current, the line voltage and the fault current on the LCD.

"Generators for short-circuit tests"

Two short-circuit generators are installed at our Kami factory for high current testing of circuit breakers and distribution panels.

Circuit breaker short-circuit shutoff tests

"Circuit breaker short-circuit tests"

In order to deliver best reliability, TERASAKI subjects both prototypes and products to a wide range of testing.
