All parameters, unless otherwise specified, are measured at ambient temperature 23ºC. Maximum make current refers to inrush current of lamp load. At ambient temperature of 85ºC, maximum allowable voltage should be reduced to 72%. Electrical life obtained at resistive or inductive load at 20A, 15VDC with suitable arc-suppression circuit attached with operating frequency of 1 ops/sec.
