    • Solid state relays should last for many years if properly protected. Watlow solid state relays include an internal voltage snubber for protection from fast transient voltages. SSRs require a small voltage to switch their load. The heat generated by the relay's switching action can accumulate depending on the cycle time and reduce the life of the relay.  This heat should be removed by mounting the SSR on an appropriately sized heat sink.  The relay should also be protected with Semiconductor Fuses which can open in tenths of a millisecond during a high fault short.  The fuse amp rating should be 125% of the relay’s load current.
