[MITSUBISHI ELECTRIC] — SR-K100LC Overlap Contact Auxiliary Relay (K100 Frame, AC/DC Coil)
Family ID: MEL-SR-K100LC
Mitsubishi Electric SR-K100LC / SRD-K100LC auxiliary relay with overlapping contacts: the a-contact closes before the b-contact opens, for circuits requiring make-before-break transfer. Contact arrangements 8a2b, 6a4b, 5a5b. Open thermal current Ith 16A, rated insulation voltage 600V. b-contact rating: closing current 20A, breaking current 3A at AC24-550V. AC-operated (SR) and DC-operated (SRD) coils. Dimensions identical to the standard SR/SRD relay. Conforms to JIS C8201-5-1, IEC 60947-5-1, EN 60947-5-1, GB14048.5. IEC 35mm rail mounting.
