Double Neutrals
System harmonics, in the face of increasing triple-N harmonic
currents Terasaki have launched a range of ACBs with double
neutrals from 800 – 6300Amps – The ‘AR-DN’. Terasaki have
the widest range of double rated neutral ACBs on the global
market.
TemCurve
TemCurve
Selectivity Analysis Software is shaped
around the extensive range of Terasaki circuit break-
ers, but also includes a large number of complimen-
tary protective devices such as High and Low Voltage
Fuses to BS88/IEC269, IDMT Relays to BS142/
IEC255. As a result,
TemCurve
can assist in protection
device grading from the transformer primary to the
point of final distribution, giving the facility to produce
overcurrent and earth fault studies.
