LTR 3500-S71 57 03511

Equipment identical with LTR 3500, plus safety temperature delimiter via a separate microprocessor controller and an additional temperature sensor connection. All-pole cutoff upon when the safety temperature is reached. The overtemperature switch-off function, nominal value +>10K is not provided. Breaking capacity: 10 A/230 V for ohm resistive loads.



All units optionally available for thermocouples! For accessories, refer to measuring device and controller temperature, resistance thermometer for Juchheim LTR.
