CompareTeSys LT3 thermistor protection unit for use with PTC probes, with automatic reset and fault indicator on front, dual voltage supply 115 or 230V AC 50/60Hz. To be used with a combination of PTC probes impedance lower than 1500 Ohm at 25°C, the trip impedance zone is 2700-3100 Ohm, the automatic reset impedance zone is 1500-1650 Ohm. It provides 2 auxiliary contacts 1NO+1NC for fault signaling. DIN rail mounting, connections by cage terminals. PTC thermistor probes DA1TT, DA1TS available (to be ordered separately). Multi-standards certified (IEC, UL, CSA), Green Premium compliant (RoHs/Reach).
