BEAMA GUIDE TO VERIFICATION OF TEMPERATURE RISE AND SHORT-CIRCUIT WITHSTAND OTHER THAN BY TEST for Low Voltage Switchgear and Controlgear Assemblies in Accordance with BS EN 61439 series
This publication is intended to provide guidance on the design veriﬁcation of an Assembly for temperature-rise limits (by assessment and comparison) and short-circuit withstand strength (by comparison).
This guide considers temperature rise veriﬁcation for Assemblies with a maximum rated voltage of 1000V a.c. or 1500V d.c. and a frequency of up to 60Hz. All other veriﬁcation requirements of the Standard must be carried out in order to fully verify an Assembly.
