Description 
The Flexible Electrical Center (FLECTM) is a configurable power 
distribution module for the heavy transportation (OTB) market. It 
accommodates circuit protection components in a compact, sealed 
footprint. Your custom electrical schematic is programmed into the 
FLECTM to create a simple “plug-and-play” system.
Each program is reviewed by Littelfuse for proper ratings, thermal 
loading, and application. The FLECTM mates to an industry standard 
connection system to provide a robust solution for heavy duty 
environments.
Contact Littelfuse for further information on FLECTM.
Features and Benefits
Cover:   Twist-on cover design allows for single-hand 
installation and removal 
PCB:   Multi-layer board allows for custom circuit 
configurations 
Base:  Includes vent for pressure equalization 
High Component Density:   Accepts multiple component footprints (i.e. 
MINI®, JCASE®, PCB -mount, etc.) in one 
package; PCB-mount components can be 
installed directly to PCB (i.e. diodes, resistors, 
relays) for space and cost savings 
InputProtection:   MEGA® fuse can be installed across M8 input 
studs to protect multiple circuits in FLECTM; 
Additional MEGA-FLEX holder can be 
interlocked to FLECTM for added fuse protection 
Accessories:   Fuse puller included in cover 
  Input stud caps provided (red and black) 
  Spare MINI® fuse positions available in cover 
  Cover tether included
