Product FAQs
10 answersWhat type of lugs are included with the BDL36050?
This breaker comes standard with EverLink lugs on both the line and load sides. These patented creep-compensating lugs help prevent loose connections over time and accept 14 AWG to 3/0 AWG aluminum or copper wire.
What is the tightening torque for the EverLink lugs on the BDL36050?
The required torque depends on the wire size used. For 14 AWG to 4 AWG wire, torque to 44.3 lb-in (5 N.m). For 3 AWG to 3/0 AWG wire, torque to 79.7 lb-in (9 N.m).
Can the BDL36050 be mounted on a DIN rail?
Yes, PowerPacT B-frame unit mount breakers feature integrated DIN rail mounting capability for standard 35mm DIN rails, in addition to traditional back pan screw mounting.
Is the BDL36050 compatible with Square D I-Line panelboards?
No, the BDL36050 is a unit mount circuit breaker designed for back pan or DIN rail mounting. For I-Line panelboards, you will need an I-Line specific B-frame breaker, such as a BDA, BGA, or BJA series.
What does the BDL prefix indicate in the BDL36050 catalog number?
In the PowerPacT B-Frame nomenclature, B stands for the frame size, D indicates the interrupting rating (25kA at 240V, 18kA at 480V), and L specifies it is a unit mount breaker with EverLink lugs on both ends.
Can the BDL36050 be used in DC applications?
Yes, this thermal-magnetic breaker is dual-rated for AC and DC applications, providing a 10kA interrupting rating at 250V DC.
Can I add control wire terminals to the EverLink lugs on this breaker?
Yes, EverLink lugs can be fitted with optional control wire terminals. These provide an auxiliary power supply of up to 10A for a control power transformer, convenience receptacle, or metering equipment.
Is the BDL36050 rated for 100 percent continuous current?
No, this breaker has a standard 80 percent continuous current rating.
Does the BDL36050 have a push-to-trip feature?
Yes, all PowerPacT B-frame 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.
What type of contact mechanism does the BDL36050 use?
It utilizes dual-break rotating contacts. This design reduces the amount of peak let-through current during a short circuit fault, enhancing downstream equipment protection.
