A2 and A3 lightweight relays offer contact arrangements of SPST N.O., SPST N.C., and SPDT and SPST N.O. on two terminals. Both styles offer PCB pin and quick-connect mounting. Contact ratings up to 40 A at 14 V dc on the A2 Series and up to 80 A at 14 V dc on the A3 Series. The contact resistance is <30 mΩ initially on both series types. Maximum switching power on the A2 Series is 630 W with maximum switching voltage of 75 V dc and maximum switching current of 40 A. The A3 Series offers maximum switching power of 1120 W, max switching voltage of 75 V dc, and max switching current of 80 A. QS9000- and ISO9002-certified manufacturing helps ensure quality and continuous reliability. Standard, RoHS, lead-free, environmentally friendly contacts (no cadmium) are AgSnO2 on the A2 Series and AgSnO2In2O3 on the A3 80-A style. Insulation resistance is 100MΩ at 500 V dc.
