PTC probe relay TeSys - LT3 with automatic reset - 115 V - 1 NC

Description

TeSys LT3 thermistor protection unit for use with PTC probes, with automatic reset, single voltage supply 115V 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 1 auxiliary contact 1NC for fault signalling. 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).
