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.
