Product FAQs
6 answersWhat is the lug torque specification for the BJL36125 circuit breaker?
The EverLink lugs require 44.3 lb-in (5 N.m) for 14 to 4 AWG wire and 79.7 lb-in (9 N.m) for 3 to 3/0 AWG wire.
Can the BJL36125 be mounted on a DIN rail?
Yes, this unit-mount circuit breaker features integrated clips for standard 35 x 15 mm symmetrical DIN rail mounting, in addition to traditional back-pan screw mounting.
Does the PowerPacT BJL36125 replace older Square D circuit breakers?
Yes, the PowerPacT B-frame series is the direct replacement for legacy Square D F-frame breakers, including the FAL and FHL series commonly used in control panels.
Is the BJL36125 suitable for reverse feeding?
Yes, standard unit-mount PowerPacT B-frame circuit breakers have sealed thermal magnetic trip units and can be safely reverse fed.
What do the letters in the BJL prefix indicate?
The B designates the PowerPacT B-frame, the J indicates the interrupting rating of 65kA at 480V, and the L specifies that the breaker comes with lugs on both the line and load ends.
What type of lugs are included with the BJL36125?
This breaker includes Square D EverLink lugs on both the line and load sides. These creep-compensating lugs are designed to prevent wire loosening caused by thermal cycling.
