Three Phase Solid State Relays
• Solid State Relay for all type of loads with integrated heatsink
• DIN rail or panel mounting
• Back to back thyristors with TMS2 technology
• 50A Thyristors size with I2t >1500A2s (*)
• 90-240VAC control voltage with input status LED
• RC+ Overvoltage protection by integrated VDR
• IP20
• Designed in conformity with UL, EN60950 and IEC60947-4-3
• No tool needed for mounting and dismounting or
DIN rail or direct mouting on panel
(*) : on request : model with I2t 5000A2s up to 20000A2s
