118BKA | Aluminium High Voltage Open-Cut Coupler

The 118BKA is rated for 800 amps with an operational voltage of 11,000 volts and features an ingress protection rating of IP68, far exceeding the Australian standard of IP55.

The 118BKA is designed for use in Non-Ex operational environments, such as open-cut and metalliferous mining, and pumps and tunnelling projects. Released in 1995, this coupler was the first design released to the Australian market that featured full phase to phase segregation with earth. The design of the 118BKA is based on AS/NZS1300 compliance, requiring the use of eight bolts to join two couplers and close the system.
