Welcome to the official website of Sanyou Lianzhong
Features:
●2 Main contacts +1 Auxiliary contact.
●Auxiliary contact can detect main contact welding in order to construct a safety circuit( lEC 61810-3)
●Contact gap:Min 3.6mm(Main contact),each contact, Min 1.0mm(Auxiliary contact)
●Applicable to inverters for solar photovoltaic power generation,AC charging piles
●Low coil holding voltage contributes to save energy
