ETS-Lindgren's LRE Series Multiple Circuit Filters are designed for moderate filtering requirements. These filters are typically used on mid-performance modular shielded rooms, screen rooms, or foil-lined rooms. LRE filters are designed for two to four wire applications. Like all ETS-Lindgren power line Filters, LRE filters are designed and manufactured to meet or exceed MIL-STD-220C, UL-1283 and/or MIL-f-15733, though none of these are UL Listed. 

Optional mounting penetration hardware is available that allows for direct installation through a shielded wall.  Please order /PEN option.

Power factor correction coils are recommended for 400 Hz filters 50A or higher.
