Universal Phoenix Contact® Equivalent Terminal Blocks

ASIUK1.5NThe ASIUKN series is comparable to the popular Phoenix Contact® UKN series in many ways, except one-ASI's Low Price! Both have a universal mounting foot, both have similar materials, shape and specifications. And both have comparable UL ratings. You make the comparisons-"Why pay the difference, if you can't tell the difference?".

The ASIUKN series shares a similar color and shape to the Phoenix Contact® UKN series. Using similar or superior materials, such as UL 94V0 housings, nickel-plated copper alloy metal bodies, and plated copper alloy screws provide protection against various environments. In fact, the ASIUKN series is so similar to the Phoenix Contact® UKN series that you can use the accessories interchangeably. If you are currently using Phoenix Contact® UKN series terminal blocks and are seeking a more cost-effective solution, you can use any remaining accessories that you may have in stock.

The ASIUKN series is an ideal terminal block family to be used in all types of control cabinet and power distribution applications. The terminal blocks range from a small 4.2mm wide version rated for 30-14 AWG wiring, 15 amps, 300 volts, up to a block 15.2mm wide that handles 18-2 AWG wire with a rating of 150 amps at 600 volts.

The ASIUKN terminal blocks include a wide range of accessories including bridges, markers, end covers, partition plates and more. A unique feature of the 5.2 and 6mm wide terminal blocks is the availability of a low-cost push-in jumper which can further reduce time and cost.

The ASIUKN series equivalents to the Phoenix Contact® terminal blocks are:
