An improved multiphase compressed-gas circuitinterrupter installation is provided having compact serviceable and inexpensive operating arrangements with an improved gas-leakage detection arrangement and system for detecting a loss of high-pressure gas in each of the multiphase circuit-breaker modules to the exclusion of the other circuit-breaker phase modules. An improved operating-linkage rod-assembly is provided extending across the front of the circuit-breaker installation, and readily available for easy servicing and adjustment, so that synchronism of the control valves in the several phase-units, or pole-units may be achieved.
