SIEMENS przekaźnik termiczny termik 3UN2110, 24VDC, 3UN2110-0AB4

- nazwa: przekaźnik zabezpieczający termicznie,- producent:SIEMENS,- model: 3UN2110-0AB4,- zabezpieczenie współpracuje z termistorem - czujnikiem temperatury PTC montowanym np. w silniku,- zasilanie: 24 VDC,- styki: 1 NO + 1 NC, 5 A,- zabezpieczenie monitoruje temperaturę silnika i wyłącza go w przypadku przegrzania,- wymiary: 96 x 96 x 23 mm,The thermistor engine protection equipment for PTC resistortemperature sensors of type 3UN2 is - in connection with PTC resistorsmeeting DIN 44081 / 082 requirements - are designed for direct temperaturecontrol of explosion-proof engines of ignition type increased safety Ex eand provided with the PTB approval sign.The switching devices 3UN2 operate in accordance with the rest currentprinciple and therefore monitor themselves against any rupture of wire. Ashort-time voltage loss of less than 200 ms does not lead to a change ofstate of the auxiliary contact assemblies. Some of the models are equippedwith an additional short-circuit identification in the sensor circuit. The unit will release, if a short circuitoccurs within the sensor circuit ( resistance in the sensor circuit < 20 ). The switching devices areprovided with a galvanic division between control and sensor circuit using AC voltage conditions(DC operation: no galvanic interruption). 3188.
