Functions and characteristics By combining a remote-operated sourcechangeover system with an integrated BA or UA automatic controller, it is possible to automatically control source transfer according to user-selected sequences. These controllers can be used on sourcechangeover systems comprising 2 circuit breakers.
Associated controllers Controller installation Functions and characteristics 0 ACP auxiliaries control plate PB100857 The auxiliaries control plate provides in a single unit: b protection for the BA or UA controller with two highly limiting P25M circuit breakers (infinite breaking capacity) for power drawn from the AC source b control of circuit-breaker ON and OFF functions via two relay contactors b connection of the circuit breakers to the BA or UA controller via a built-in terminal block.
