B.E. 2511(1968): Amending to Thai Industrial Standard for Residual Current Operated 
Circuit -Breakers without Integral Overcurrrent Protection for Household and Similar Uses 
(RCCBS) - Part 1: General Rules (Amendment N o. 1) (120 page(s), in Thai)  
6. Description of content:  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 prot ection (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 c urrent, 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.  G/TBT/N/THA/498
