*1OCPD : Over Current Protection Device
*2IEC60947-6-1 Requirements :
IEC60947-6-1 Class CB : ATS provided with over current releases and the main contacts of which are capable of making and are intended for breaking short circuit currents.
IEC60947-6-1 Utilization Category AC-33A :
Motor loads or mixed loads including motors, resistive loads and up to 30% incandescent lamp.
*3The purpose of aluminum base design :
To prevent occurrence of eddy current (Foucault current) which reacts with steel board and cause excessive heat.
The use of aluminum base plate also greatly reduces product weight.
