DESCRIPTION

UNIPOWER’s UNIFLEX

®

 distribution panels 

provide the ultimate flexibility in combining 

fuses, circuit breakers and/or an LVD in a dual 

(A/B) panel.  A GMT section provides 10 fuses 

and a circuit breaker section, 1-6 breakers.

A low-voltage disconnect section is 

configured at the factory for either battery 

or load disconnect and can have an optional 

bypass switch. A battery circuit breaker is 

standard.

Each A and B section has an LED alarm 

indicator and Form C relay contacts.

The A and B Sections are isolated and can be 

configured independently at the factory for 

12, 24 or 48 VDC, positive or negative ground.

The panels are only one mounting position 

(1.75 inches) high and come with brackets 

that permit mounting in either a 19- or 

23-inch relay rack. They can be mounted 

from the front of the rack with offsets every 

quarter-inch from front to back to align with 

existing rack mounted equipment.
