ASM Series current sensors operate as the sealed secondary of a current transformer while the conductor
carrying the current to be measured functions as a one turn primary. Measurement accuracy can be
improved by increasing the number of primary turns. Applications include detection of branch circuit
overload and load drop or shutdown.
