AgSnO are kinds of environment-protective and non-poisonous contact welding. In gerneral, on the condition of larger current, AgSnO have higher arc erosion resisitance than AgCdO. In the lamp or capacitive load, AgSnO show better than AgCdO, AgNi on the abillity of anti-impulse current...
AgSnO contact are widely used in medium heavy-capacity contactors, AC/DC power relays, automotive electrical appliances and small medium-capacity circuit breakers of low voltage.
