This study presents an analysis technique that can consider all variables which are needed in the design of short circuit current capability of electrical contacts. Required variables in the design are material of contact, contacting area, applied force, asperity of surface, current and so on. Short circuit current capability test was carried out for the interrelation of design variables and the verification of analysis technique. Temperature rise equation of the contacts was obtained from the test results, and also, a standard that is criterion of the occurrence availability of melting or spot of contact surface from test results was established.
