Solid state relay 3 phase block type with heat sink and fan >25 amps Gefran GTZ
3 phase SSR assemblies in the GTZ series( from Gefran) are designed for resistive and inductive loads at high power levels. They are capable of continuous fast switching and retain full rating to 40C ambient. All versions are protected against overvoltage and several different alarm options exist for temperature. Part numbers shown for reference are DC trigger and without options but rated to 480VAC. These are zero cross switching and use back to back SCRs for switching.
- Current ratings 25, 40 and 55 amps per phase
- Voltages 480 or 600 VAC
- Optoisolation 4000Vrms input to output
- DIN rail mounting
- Replaceable 3 phase SSR block in GZ series
- Recommend use of fast fuses on the connected load
