Product FAQs
7 answersHow is the BDL26040 circuit breaker mounted?
This unit mount breaker can be installed using traditional back pan mounting with screws or snapped directly onto a standard 15 x 35 mm DIN rail using its integrated mounting channel.
What are the torque specifications for the lugs on the BDL26040?
The EverLink lugs require 44.3 lb-in (5 N.m) of torque for 14 to 4 AWG wire, and 79.7 lb-in (9 N.m) of torque for 3 to 3/0 AWG wire.
Can the PowerPacT BDL26040 replace older Square D circuit breakers?
Yes, the PowerPacT B-frame series is the designated replacement for legacy Square D F-frame breakers, such as the FAL and FHL series commonly used in control panels.
What does the D in the BDL26040 part number signify?
The D indicates the interrupting rating level for this PowerPacT B-frame breaker, which provides 18kA at 480VAC and 14kA at 600Y/347VAC.
What does the L in the BDL26040 catalog number indicate?
The L indicates that this is a unit mount circuit breaker equipped with lugs on both the line and load ends, as opposed to an I-Line plug-on connection.
What type of wire terminals are included with this breaker?
The BDL26040 comes with patented EverLink lugs on both the line and load ends. These lugs are designed to maintain constant contact pressure on fine stranded or rigid aluminum and copper conductors, reducing loosening over time.
Does this breaker feature a push-to-trip button?
Yes, all PowerPacT circuit breakers include an integral push-to-trip button on the cover to manually trip the breaker and verify the mechanical operation of the trip mechanism.
