Panel mount single pole types are available with AC outputs up to 100A at 530V and DC outputs including 100A at 30V and 12A at 500V. Three phase panel mounting models feature AC outputs up to 60A at 440V AC with the option of phase loss protection. Panel mounting Dual Relay types - which include two complete and independent relays in a single package, each capable of handling AC loads up to 50A 440V – are also included, as are a selection of PCB devices with AC outputs up to 5A 280V and DC outputs of 2A 100V.

Comments Simon Dugdale, Applications Engineer at Hawco: “Solid state relays can replace electromechanical relays or contactors in many applications. With no moving mechanical parts to wear out or arcing contacts to deteriorate, they are extremely reliable with a very long service life.”

Typical applications include: heater controls; food equipment; industrial lighting; fire and security systems; dispensing and vending machines; production equipment; traffic control equipment; medical devices; instrumentation systems; motor control panels and manufacturing machinery.
