may nakalagay po kasi doon sa contact specs nya na
Rated load in AC1
Rated load in AC15 (230 VAC)
ano po ba ung tinutukoy dun? ung phases po ba nung AC voltage?
AC1 And AC15 refer to load categories defined by IEC 158-1 for contacts of relays or contactors.
AC1 refers to non inductive (purely resistive) load thus you can usually get higher VA loads
AC15 refers to inductive loads thus you get lower VA loads.
In between are others like:
AC2 - for starting of slip-ring motors
AC3 - for starting of squirrel-cage motors and switching off only after the motor is up to speed. (Make LRA, Break FLA)
AC4 - starting of squirrel-cage motors with inching and plugging duty. Rapid Start/Stop. (Make and Break LRA)
For more info try to get info abour IEC 158.
