• Simple snap onto DIN rail or attach with screws to a panel for secure mounting

The AG-LC Series ground fault relay features an innovative design ideal for monitoring larger circuits. The 2011 NEC added Section 555.3 to require ground fault protection of the main overcurrent device feeding marinas and boat yards. These services often carry up to 800 amps; most relay designs will not allow the conductors to pass through a single sensing ring. By designing a relay in a large solid-core housing, the conductors will not have to be passed through a separate sensing device like a zero-sequence current transformer. This design makes monitoring larger circuits a breeze, whether to protect boaters or large equipment like amusement park rides or gantry cranes.
