Schneider Electric LV848891SP Differential Ground Fault Interface Module

Schneider Electric LV848891SP is a Modified Differential Ground Fault (MDGF) summing module designed as a spare part for MasterPact MTZ1, MTZ2, and MTZ3 circuit breakers. It forms part of Schneider Electric's MDGF earth-fault protection scheme for MasterPact installations, interfacing with MTZ-series breakers to enable coordinated ground-fault protection in high-power low-voltage switchgear. Compatible with MTZ1, MTZ2, and MTZ3 frames, the LV848891SP is intended for maintenance and replacement within existing MTZ-based systems, not for standalone operation. Installation and service should be performed by qualified personnel in accordance with Schneider Electric safety guidelines and local regulations. This module is typically used in industrial power distribution environments where reliable earth-fault protection is required to protect equipment and maintain system safety.
