Product FAQs
9 answersCan the Square D BDL36080 be mounted on a DIN rail?
Yes, this PowerPacT B unit mount circuit breaker features integrated DIN rail mounting capabilities, allowing it to snap onto a standard 35mm DIN rail or be traditionally mounted to a back pan using screws.
What is the advantage of the EverLink lugs on the BDL36080?
The factory-installed EverLink lugs feature a patented design that helps prevent the loosening of cables over time. This maintains a constant, low-resistance connection on the conductor, reducing the need for periodic retorquing.
What does the "L" signify in the BDL36080 catalog number?
The "L" indicates the termination option. It means the breaker is a unit-mount configuration with EverLink lugs installed on both the line and load ends. For an I-Line plug-on version, the third letter would be an "A", resulting in catalog number BDA36080.
What does the "D" stand for in the BDL36080 part number?
The "D" denotes the specific interrupting rating tier within the PowerPacT B-frame family. It signifies a short-circuit current rating of 25 kA at 240V, 18 kA at 480V, and 14 kA at 600Y/347V AC.
How does the BDL36080 compare to the BGL36080 or BJL36080?
They share the same 80A rating, physical dimensions, and EverLink lugs, but differ in their maximum interrupting capacities. The BDL has a standard 18 kA rating at 480V, while the BGL offers 35 kA, and the BJL provides 65 kA at the same voltage.
How can I verify the mechanical operation of the BDL36080 without a live fault?
You can manually exercise the trip mechanism using the push-to-trip button located on the front cover. This safely tests the mechanical linkages and ensures the breaker will operate correctly during a fault condition.
Can I add a control wire tap to the lugs on this breaker?
Yes, EverLink lugs with integrated control wire terminals are available as factory modifications or field-installable kits. These provide an auxiliary power supply up to 10A for metering or control power transformers without altering the primary wire connection.
Does this breaker feature adjustable or fixed trip settings?
The BDL36080 utilizes a fixed thermal-magnetic trip unit. The thermal element provides long-time overload protection, while the magnetic element provides instantaneous short-circuit protection. Both trip thresholds are factory calibrated and non-adjustable.
Is the BDL36080 suitable for DC applications?
Yes, this 3-pole breaker is rated for DC applications up to 250V DC with a 10 kA interrupting capacity. Ensure proper wiring configurations per the manufacturer guidelines based on the grounded or ungrounded nature of the DC system.
