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.
