Middle Atlantic MPR-6A Datasheet

Next Generation
MPR Series

modular raceway system

• Lightweight raceway with back-mount support clip that allows mounting
in any position on a vertical or horizontal axis

• Raceway available in any of (4 ) standard lengths or can be cut to any
custom length of 2” increments. See chart on next page for usable
mounting space.

• Modules can be positioned anywhere along the raceway in 2” increments

• Basic and controlled (dry contact) power modules available in 15A, 20A & 30A

features:

· USC-6R, MPR-SEQA, MPR-SEQ-1CA or any maintained dry contact
can be used for control

• Standard and isolated ground modules

• NEMA, IEC, Twist-lock, and Neutrik receptacles

• Convenient genderless connectors ensure fast & safe assembly
(no hardwired inter-chassis connections)

• An open deep raceway, with no cross divider interference ensures fast
and easy assembly

· Threaded grooves along length of extrusion allow attachment of cable
management ties for low voltage control

• Multiple junction box options supports different wiring applications & circuit
termination capacity

• Laser Knock-Outs ( LKO ) in end caps for power connections

• Custom laser engraving available

• Standalone modules available (remote access)
