Guidance concerning the permissible temperature rise for parts of electrical equipment, in particula...
Is intended for guidance in estimating the permissible values for temperature and temperature rise of component parts of electrical equipment carrying current under steady state conditions. The present report is intended to supply: - general data on the structure of electric contacts and the calculation of their ohmic resistance; - the basic ageing mechanisms of contacts; - the calculation of the…
Low-voltage switchgear and controlgear - Part 6-2: Multiple function equipment - Control and protect...
Applies to control and protective switching devices (or equipment) (CPS), the main contacts of which are intended to be connected to circuits of rated voltage not exceeding 1 000 V a.c. or 1 500 V d.c. CPS are intended to provide both protective and control functions for remotely controlled circuits. They may also fulfil additional functions, such as isolation.
