Although it measures only 35.5 x 35.5 x 33 mm, the J7KNU contactor has a capacity of 2.2 kW AC3 and is available in three- and four-pole versions with AC or DC coils, and as a reversing contactor with mechanical interlock.
Typical applications for the new contactors include electronic systems interfacing with power supply circuits, motor control in washing machines and similar equipment, motor control in safety barriers and doors, fan control in air conditioning systems, and packaging machinery. A full 3 mm contact opening enhances the safety and reliability of the contactors, and for ease of use in motor control applications, they can be supplied as interlocked pairs mounted on the same base.
Installation of the J7KNU contactors is straightforward, as they are designed to fit 15 mm DIN rails for use in small distribution boxes. Furthermore, the J75KN snap-in adapter makes the J7KNU compatible with standard 35 mm DIN rails as well. Large screw clamp terminals are also included, enabling quick and easy wiring and eliminating the frustration of working with very small terminals.
Finally, it should be noted that the J7KNU contactors have a temperature range from -40 to +60 °C, making them a reliable option for use even in the most demanding environments.
