Residual current operated circuit-breakers without integral overcurrent protection for household uses (RCCBs) - Part 1: General rules (Second Revision) (IEC 61008-1:2010, IDT)
MS IEC 61008-1:2012
Status : 2nd Revision
Format : PDF

This Malaysian Standard applies to residual current operated circuit-breakers functionally independent of, or functionally dependent on, line voltage, for household and similar uses, not incorporating ....Read more overcurrent protection (hereafter referred to as RCCBs), for rated voltages not exceeding 440 V a.c. with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A, intended principally for protection against shock hazard. 
These devices are intended to protect persons against indirect contact, the exposed conductive parts of the installation being connected to an appropriate earth electrode. They may be used to provide protection against fire hazards due to a persistent earth fault current, without the operation of the overcurrent protective device.

RCCBs having a rated residual operating current not exceeding 30 mA are also used as a means for additional protection in case of failure of the protective means against electric shock.

ELECTROMAGNETIC COMPATIBILITY (EMC) – PART 2-2: ENVIRONMENT – COMPATIBILITY LEVELS FOR LOW-FREQUENCY CONDUCTED DISTURBANCES AND SIGNALLING IN PUBLIC LOW-VOLTAGE POWER SUPPLY SYSTEMS (FIRST REVISION) (IEC 61000-2-2:2002, IDT)
MS IEC 61000-2-2:2005 (CONFIRMED:2011)
Status : 1st Revision
Format : PDF

This Malaysian Standard specifies the conducted disturbances in the frequency range from 0 kHz to 9 k Hz, with an extension up to 148.5 kHz specifically for mains signalling systems. It gives compatib ....Read more ility levels for public low voltage a.c. distribution systems having a nominal voltage up to 420 V, single-phase or 690 V, three-phase and a nominal frequency of 50 Hz or 60 Hz. 
The compatibility levels specified in this draft Malaysian Standard apply at the point of common coupling. At the power input terminals of equipment receiving its supply from the above systems the severity levels of the disturbances can, for the most part, be taken to be the same as the levels at the point of common coupling. In some situations this is not so, particularly in the case of a long line dedicated to the supply of a particular installation, or in the case of a disturbance generated or amplified within the installation of which the equipment forms a part.

For the purposes of this standard, a distorting installation means an installation (which may be a load or a generator) that produces harmonics and/or interharmonics. The primary objective is to provide guidance to system operators or owners on engineering practices, which will facilitate the provision of adequate service quality for all connected customers. In addressing installations, this standard is not intended to replace equipment standards for emission limits. Close

ELECTROMAGNETIC COMPATIBILITY (EMC) - PART 3-11: LIMITS - LIMITATION OF VOLTAGE CHANGES, VOLTAGE FLUCTUATIONS AND FLICKER IN PUBLIC LOW-VOLTAGE SUPPLY SYSTEMS - EQUIPMENT WITH RATED CURRENT ? 75 A AND SUBJECT TO CONDITIONAL CONNECTION (IEC 61000-3-11:2000, IDT)
MS IEC 61000-3-11:2005 (CONFIRMED:2011)

This Malaysian Standard is concerned with the emission of voltage changes, voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system. 
It spec ....Read more ifies the limits of voltage changes produced by equipment tested under specified conditions.

This part of IEC 61000 is primarily applicable to electrical and electronic equipment having a rated input current from 16 A up to and including 75 A, which is intended to be connected to public low-voltage distribution systems having nominal system voltages of between 220 V and250 V, line-to-neutral at 50 Hz, and which is subject to conditional connection.

This part of IEC 61000 is also applicable to equipment within the scope of IEC 61000-3-3 that does not meet the limits when tested or evaluated with reference impedance Zref and is therefore subject to conditional connection. Equipment which meets the requirements of IEC 61000-3-3, is excluded from this part of IEC 61000.
