Phoenix Contact 3210237 The maximum current capacity of the component terminal block is determined by a built-in diode, specifically the 1N4007, with a reverse voltage rating of 1300V and a maximum continuous current of 0.5A. The nominal current value when the integrated diode is used remains at 0.5A, allowing for push-in connections to be made through the block, which has a rated cross-sectional area of 2.5mm² and can accommodate various sizes from 0.14mm² to 4mm², with three different mounting options (NS35/7.5, NS35/15) and a gray color.
