Description
Built for commercial power distribution, the Square D BDL36020 is a 20A, 3-pole MCCB. As part of the PowerPacT B-Frame series, it provides dependable thermal-magnetic protection. This unit-mount breaker is designed for industrial control panels and switchboards. It offers a compact footprint and acts as a direct substitute for the legacy FAL36020. With an 18kAIC rating at 480VAC, it includes EverLink creep-compensating lugs that maintain constant pressure on wiring to reduce maintenance.Specifications

Product FAQs
7 answersWhat are the EverLink lugs included on this breaker?
EverLink is a patented lug technology by Schneider Electric that maintains constant pressure on the wire. This compensates for thermal cycling and cable creep, ensuring a secure, long-term connection without the need for periodic retorquing.
Can the BDL36020 be installed in a Square D I-Line panelboard?
No, this specific catalog number is a unit mount breaker designed for DIN rail or traditional back pan mounting. For I-Line panelboards, you need a B-frame breaker with an I-Line mounting prefix, such as the BDA, BGA, or BJA series.
Is the BDL36020 suitable for reverse feeding?
Yes, standard unit mount PowerPacT B-frame circuit breakers feature sealed thermal-magnetic trip units and are approved for reverse feeding applications.
Does this breaker support field-installable accessories like shunt trips?
Yes, PowerPacT B-frame breakers feature a standardized accessory pocket accessible from the front face. This allows for quick, clip-in installation of electrical auxiliaries like MX shunt trips, MN undervoltage releases, and OF/SD indication contacts without opening the breaker case.
What legacy Square D circuit breaker does the PowerPacT B-frame replace?
The PowerPacT B-frame is the modernized replacement for legacy Square D 100A-frame breakers, such as the FAL and FHL series. It delivers updated technology and a smaller footprint for industrial control panels.
Can this breaker be mounted directly to a DIN rail?
Yes, unit mount PowerPacT B-frame circuit breakers include integrated DIN rail mounting capability alongside traditional back pan screw mounting, providing flexibility for industrial control panel installations.
How does the dual-break rotating contact design improve performance?
PowerPacT B-frame breakers utilize a dual-break rotating contact mechanism that rapidly repels during a short circuit. This extinguishes the fault current before it fully develops, significantly reducing let-through energy and improving downstream equipment protection.
