TemPower2 is the world’s first “Double Break" ACB, having two breaking contacts per phase. The unique pole structure means that the short time withstand rating (lew , isec) is equal to the service short circuit breaking capacity (les) for all models. Full selectivity is guaranteed up to the full system fault level. TemPower2 ACBs have the world’s smallest depth resulting in space saving in switchboards. Compact size for high packing densityNo extra arc space required for clearance.
TemPower2 is the only ACB which offers time-current characteristics to 3 different standards: IEC 60 947-2 (low voltage circuit breakers). IEC 60 255-3 (electrical relays). Uoyds Register of Shipping (for marine generator protection). All models have LSI protection. Rated Operational Voltage [Ue] (V.50/60Hz)-690 AC Rated Insulation Voltage [Ui] (V.50/60Hz)-1000
