Accidental Overload Test

IEC 60115-1 4.26

4 times RCWV for 1 Min.

No evidence of flaming

or arcing

Note:

RCWV (Rated Continuous Working Voltage):

The DC or AC (rms) continuous working voltage corresponding to the rated power is determined by the following

formula:

V=√(P X R)

or max. working voltage whichever is less

Where

V=Continuous rated DC or

AC (rms) working voltage (V)

P=Rated power (W)

R=Resistance value (Ω)
