Watlow | Solid State Power Switching Devices 

Watlow solid state power switching devices complement the rapid switching required by PID temperature controllers and help deliver optimum system performance and service life. They are available in 1-phase and 3-phase/2-leg and 3-leg configurations, feature touch-safe terminations, input indicators, zero-cross, random or phase-angle fire options, ratings from 18 to 1,000 amperes and agency approvals including CE and UL® 508. Various configurations offer short circuit current ratings (SCCR) of 200,000 amperes, extensive system and heater diagnostic capabilities, heater bake out, integrated heat sinks, on-board fuses, RoHS compliance and serial communications.

Watlow DIN-A-MITE® and E-SAFE II power switching devices provide convenient DIN-rail mount packages and are a good replacement for mercury displacement relays.

Additionally the EZ-ZONE ST offers an integrated temperature and process controller with optional over- and under-temperature limit and safety shutdown contactor.
