Product FAQs
8 answersHow does the BGL36050 mount inside an enclosure?
This unit mount breaker can be fastened directly to a backpan using screws or snapped onto a standard 15 x 35 mm DIN rail without requiring additional adapter plates.
What type of lugs are included with this breaker?
It features patented EverLink lugs on both the line and load ends. These creep-compensating lugs are designed to maintain constant pressure on wire connections, reducing the risk of loosening over time.
Can this breaker be used in DC systems?
Yes, it is rated for up to 250VDC with an interrupting capacity of 20kA. When used in DC applications, the poles must be wired in series according to the manufacturer's DC wiring diagrams based on your specific grounding scheme.
What does the G in the BGL36050 part number signify?
The G indicates the interrupting rating tier for the PowerPacT B-frame. It signifies a breaking capacity of 35kA at 480VAC. Other common tiers in this family include D (18kA), J (65kA), and L (100kA).
Is the trip unit on the BGL36050 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the continuous current (overload) and instantaneous (short-circuit) pickup levels are fixed and cannot be adjusted in the field.
Can I add field-installable accessories to this breaker?
Yes, the PowerPacT B-frame supports field-installable electrical accessories, such as shunt trips, undervoltage releases, and auxiliary contacts. These mount directly into the accessory compartments located under the front cover.
Does this breaker provide positive contact indication for safe isolation?
Yes, the handle includes clear visual indication of the ON, OFF, and TRIPPED positions. The OFF position provides positive contact indication and is suitable for safe isolation when performing panel maintenance.
Can the BGL36050 replace older Square D legacy breakers?
Yes, the PowerPacT B-frame is designed to the same 1.5-inch per pole width as the legacy F-frame breakers. It serves as a modern, compact substitute for discontinued FAL36050 and FHL36050 breakers without requiring blank fillers.
