Introduction
HIC4xxA “Automatic Transfer Switching Equipment” (ATSE) is designed for use in power systems for
the safe transfer of a load supply between a normal and an alternate source. The changeover is done in
open transition and with minimum supply interruption during transfer ensuring full compliance with IEC
60947-6-1, GB 14048-11 and other international TSE standards as listed.
The HIC4xxA is a full load break (switch type) derived transfer switching equipment where the main
components are proven technology devices also fulfilling requirements in IEC 60947-3 standards.
As a Class PC ATSE, the HIC4xxA is capable of “making and withstanding short circuit currents”
assigned to IEC 60947-3 utilization categories of up to AC23A, GB 14048-11, IEC 60947-6-1 and
equivalent standards with utilization categories of up to AC33B.
HIC4xxA transfer switches ensure:
• Power Control and Safety between a normal and an alternate source.
• A complete product delivered as a fully assembled and tested solution.
• Intuitive HMI for emergency / local operation.
• Integrated and robust switch disconnection.
• Window with clearly visible position indication I – 0 - II.
• An inherent failsafe mechanical interlock.
• Stable positions (I – 0 – II) non affected by typical vibration and shocks.
• Constant pressure on the contacts non affected by network voltage.
• Energy Efficient with virtually no consumption whilst on the normal, alternate or off positions.
• Extremely rugged, error free and built in padlocking facility (configurable).
• Straight forward installation with effective ergonomics.
• Simple motorization control interface.
• ATS configuration through 4 potentiometers and DIP switches.
• Auxiliary contacts for switch positions I – 0 - II (optional).
• “Product availability” output.
• Ample accessories to suit specific requirements.
• Fully integrated ATS controller specifically designed for Mains / Mains and Mains / Genset
applications.
