Terasaki’s
TemPower2
A.C.B is the result of
an intensive market
research program
which took into ac-
count the require-
ments of switchboard
builders, consultants
and end users.
TemPower2
Air Circuit
Breaker is one of the
smallest in the market
with a 1 second rating

Innovations
New design built-in UVT

controller to be mounted on the side of the ACB.
New Protection Relay range the AGR-B.
The new AGR-B
range will have an improved LCD display, which will include
additional features such as an Ammeter, Zone Interlocking
and Multi/Power Meter capabilities. This will also mean
some changes to previous closing circuit configurations.
