3TF2 contactors, 3-pole, 2.2 ... 4 kW

Applies to 50/60 Hz coil:At 50 Hz, 1.1 x Us, side-by-side mounting and 100 % ON period the max.ambient temperature is +40 °C.2) The 3TX4 490-1J additional load module is recommended for higher residualcurrents (see "Accessories and Spare Parts").3) The OFF-delay of the NO contact and the ON-delay of the NC contact areincreased if the contactor coils are attenuated against voltage peaks(noise suppression diode 6 to 10 times; diode assemblies 2 to 6 times,

varistor +2 to 5 ms).
