Low voltage contactors type CC - NEW
NEW
CC capacitor contactors are suitable for switching low-inductive and low-loss capacitors in capacitor banks, without and with reactors. CC capacitor contactors are designed to meet capacitor duty application. Contactors are fitted with block of three early make auxiliary contacts in series with six damping resistors - 2 per phase. These auxiliary contacts limit peak current in first stage of switching. Subsequently the nominal current is transferred through main contacts which are switched in the next stage and the auxiliary contacts are switched-oof at the same time.
The main features:
- electrical life
- reduced watt loss during "ON" condition
- prolonged lifetime of capacitor
