Description
TeSys LT3 thermistor protection unit for use with PTC probes, with automatic reset, single voltage supply 24V DC. 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 1 auxiliary contact 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).
