Overview
The Merlin Gerin DPNA VIGI B16 is an industrial-grade residual current circuit breaker (RCD) integrating both earth leakage protection and thermal-magnetic overcurrent sensing in a single DIN-rail module. Built for single-phase circuits, this Multi 9 series device delivers proven reliability in electrical installations requiring dual protection against ground faults and overload conditions. Part number 19793 represents Schneider Electric’s commitment to compatibility and performance in demanding European electrical markets.
