224BKA Range | 22,000 Volts | 425 Amp | High Voltage Half Coupler

Rated for 425 amps with an operating voltage of 22,000 volts, the 224BKA hold an ingress protection rating of IP68.

Re-released in 1996 after redevelopment, the original 224BKA was designed in 1989. A feat of electrical engineering, this genderless coupler was the first coupler in the world rated to withstand up to 22,000 volts. Suitable for use in Non-Ex operational environments, such as opencast and metalliferous mining, and pumps and tunnelling projects, the 224BKA requires just 4 bolts to open and close the coupler system.
