Product FAQs
4 answers
Is the BDL26050 compatible with Square D I-Line panelboards?
No, the BDL26050 is a unit-mount breaker designed for surface mounting on a backpan with feed-thru lugs. For plug-on I-Line panelboards, you need an I-Line B-frame breaker, which typically starts with the prefix BDA instead of BDL.
Does this B-frame breaker support direct current applications?
Yes, this 2-pole breaker is rated for use in DC circuits up to 250VDC. It provides a 10kA interrupting capacity at 250VDC, making it suitable for DC control panels and specialized equipment.
Can the trip elements on this breaker be adjusted for specific loads?
No, the thermal magnetic trip unit on this 50A breaker features fixed long-time (overload) and fixed instantaneous (short-circuit) settings. They cannot be adjusted in the field.
What wiring is supported by the factory lugs on this breaker?
The line and load side lugs accept 14 AWG to 3/0 AWG wire. They are certified for use with both aluminum and copper conductors. Ensure proper torque values are applied as indicated on the device label during installation.
