Abstract (in Japanese) (See Japanese page) 
(in English) Electrical contacts are separated at constant speed and break arcs are generated in a 200V-450VDC/10A resistive circuit. The break arcs are extinguished by magnetic blow-out. Arc duration for the Ag, Cu, W, Mo, C, Pd and Ni contact pairs is investigated for each supply voltage and arc duration for the Ag and other material contacts is compared. As a result, for the Ag and Cu contact pairs, the arc duration for Cu contacts is longer than that of Ag contacts. For the W and Mo contact pairs, the arc duration for W contacts is almost the same as that of Ag contacts, while the arc duration for Mo contacts is longer than that of Ag contacts. For the Ag and C of high sublimation temperature and Ni of magnetic material, the arc duration for C and Ni contacts considerably becomes longer than that of Ag contacts. For the Ag and Pd of low thermal conductivity, the arc duration for Pd is longer than that of Ag contacts.
