PKZ Compact Starters and High-Capacity Compact Starters: Unbeatable even at 500 V
What counts is operational continuity
More than 80 % of low-voltage switchgear assemblies throughout the world are used in mains systems up to 400 V. Compact starters and high-capacity compact starters from the PKZ 2 system is also designed for rated operational voltages of 500 V and 690 V. They control high short-circuit currents here as well.
PKZ 2 high-capacity compact starters are inherently short-circuit proof for rated operational currents of up to 40 A (30 kW). Short-circuit currents of up to 100 kA can thus be switched safely. At the same time, the units satisfy IEC/EN 60947-4-1 requirements regarding type "2" coordination. This ensures very high operational continuity. Downtimes after a short-circuit are reduced to a minimum.
PKZ 2 compact starters represent a more economic solution for standard applications. They comply with IEC/EN 60947-4-1, type "1" coordination.
