Zero-Crossing SSRs Have Built-In Fuses

Offering built-in replaceable semiconductor fuses and automatic shutdown on overtemperature conditions, a series of zero-crossing solid-state relays (SSRs) is easily field-upgradable with future options. These can include special over- and under-voltage sensing inputs of 20 to 40 mA or zero to 10V, current sensing, sensing of lack of signal output and an A.S. interface. The intelligent relay is DIN rail- or panel-mountable and has integrated heat sink, optical isolation, touch-safe packaging and UL, CSA and CE Mark conformance. They're available in 50A, 75A or 100A versions with 48 to 660 vac outputs.
