This is the Suntech SEM-2417 automotive relay. A 24 volt, 30/40 amp, 5-pin SPDT (single pole, dual throw) relay. Sold as a single relay.

Check your voltage before ordering. This is the 24 volt version, for buses, transport trucks and heavy equipment. Cars and light trucks are 12 volt and need the SEM-1417 instead. Fitting the wrong one will not work.
