MINIATURE AND MOLDED CASE
CIRCUIT BREAKERS
[8] Four MDGF sensors (phase + 1 neutral) are required for MTZ2; eight MDGF sensors are required for MTZ3. For SGR system only one sensor (neutral) is required for MTZ2; two sensors for
MTZ3
[9] Oversized neutral protection = 1.6 Ir where Ir = long time pick-up
[10] Oversized neutral protection = 1.6 Ir where Ir = long time pick-up.
