The Thai Industrial Standards Institute (TISI) has proposed to amend the Thai Industrial Standard for residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBS)- Part 1: General Rules.
This standard applies to residual current operated circuit-breakers functionally independent of, or functionally dependent on, line voltage, for household and similar uses, not incorporating overcurrent protection (hereafter referred to as RCCBs), for rated voltages not exceeding 440 V a.c. and rated currents not exceeding 125 A, intended principally for protection against shock-hazard.
The main amendment includes standard values of rated residual operating current, which modified to be 0.006 - 0.01 - 0.015 - 0.03 - 0.1 - 0.2 - 0.3 - 0.5 - 1 A as stated in 5.3.3.
