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.
