Providing reliable thermal-magnetic protection, the Square D BGA160205 is a 1-pole, 20A PowerPacT B-Frame molded case circuit breaker. It features fixed long-time and instantaneous (LI) trip functions. This component installs into Square D I-Line panelboards and switchboards. It also functions as an exact replacement for the legacy FA16020C breaker. Built with a Phase C connection, it delivers a 65kA interrupting rating at 240VAC and includes a visual trip indicator.
What does the "5" at the end of the BGA160205 catalog number indicate?
The "5" suffix indicates that this 1-pole I-Line circuit breaker is factory-configured for a C-phase connection in the panelboard. For comparison, A-phase connections use a "1" suffix, and B-phase connections use a "3" suffix.
What does the "G" in the BGA160205 part number represent?
The "G" designates the interrupting rating tier within the Square D PowerPacT B-frame series. It signifies a breaking capacity of 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
What does the "A" in the BGA160205 catalog number mean?
The "A" indicates the termination type for this PowerPacT breaker. It specifies that the breaker has an I-Line style plug-in connection on the line side and mechanical lugs on the load side.
Which panelboards are compatible with the BGA160205 circuit breaker?
This PowerPacT B-frame breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It utilizes a plug-in I-Line style connection that mounts directly onto the bus assembly.
Can the BGA160205 be used in DC power systems?
Yes, this breaker is rated for 125VDC applications. It provides an interrupting capacity of 20kA at 125VDC, making it suitable for specific direct current control and distribution circuits.
Is this breaker suitable for 277V or 347V lighting circuits?
Yes, this 1-pole breaker has a maximum AC voltage rating of 600Y/347VAC. This allows it to be safely applied in 277V and 347V single-phase circuits, providing 35kAIC at 277V and 18kAIC at 347V.
What safety procedures are required when installing this I-Line breaker?
Always de-energize the I-Line panelboard or switchboard before installing or removing plug-in breakers. Verify that the power is completely off using a properly rated voltage sensing device and wear appropriate personal protective equipment (PPE) in accordance with NFPA 70E guidelines.
