What are the requirements for self-ballasted lamp load control cabinets in the IEC 60669-1 standard?
According to IEC 60669-1-2017, clause 19.3, switches used for the control of self-ballasted lamps shall withstand the electrical and thermal stresses that occur when controlling self-ballasted lamp circuits without undue damage or other detrimental effects.
The expected short-circuit current (r. m s.) of the power supply for testing shall be between 3 kA and 4 kA at cos$=0.9±0.05 (hysteresis) F shall be a copper wire fuse having a nominal diameter of 0.1 mm and a length of not less than 50 mm R1 shall be a resistor limiting the current to approximately 100 A. The switch shall have an appropriate length of two-core cable. The double-core cable shall be of such length that the resistance of the test circuit to the load, R3, is equal to 0.25 Ω. When the rated current of the switch under test does not exceed 13 A, the cross-sectional area of the double-core cable is 1.5 m m²: when the rated current of the switch under test exceeds 13 A, but does not exceed 20 A, the cross-sectional area of the double-core cable is 2.5 m m. The test load shall be of the same type as that shown in Fig. 14, with a copper fuse of nominal diameter 0.1 mm and length of not less than 50 mm.
The load for testing shall be consistent with Figure 14b (see Appendix C). The maximum peak current and maximum inrush current I2t values are given in Table 19.
Note 1: R2 for the total series resistance of the light circuit, including the ESR (equivalent series resistance) value of the capacitor.
