Description
Choose the 47KMFDB3 when one marine main power feed needs to split into as many as three separately fused amplifier circuits. It uses marine MRBF fuses so each downstream branch can be protected independently. This is the power-distribution choice; use the 47KMDB3 when the job is organizing grounds instead.
