Square D BGA260404 - 40 A, 2-Pole Plug-In Circuit Breaker | AmpState

The Square D BGA260404 is a 40A, 2-pole plug-in molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection for panelboards and load centers. Built for fast, secure protection, this unit sits squarely in residential, commercial, and light industrial applications where reliable power management matters.

• Fast plug-in connection enables quick installation and easy replacement, minimizing downtime during service or upgrades.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining thermal overload sensing with instantaneous magnetic response to short circuits, helping prevent damage to wiring and connected equipment.
• Compatibility with matching OEM loadcenters and panelboards ensures proper fit, listings, and predictable performance within your existing system.
• 2-pole design protects both conductors of a circuit and ensures simultaneous disconnection, enhancing systemic safety for multi-wire branch circuits.
• 40A rating makes it suitable for higher-load branches common in home workshops, small offices, or light industrial setups where robust protection is needed without sacrificing space in the panel.

Why choose this model? The BGA260404 is purpose-built for quick swaps in live panel environments, reducing installation complexity while preserving precise protection characteristics. Its thermal-magnetic mechanism is engineered for repeatable performance, meaning you get consistent trip behavior across temperature variations and load conditions—important for maintaining system reliability in real-world scenarios.

Who is this ideal for? Electricians and maintenance professionals upgrading or refurbishing panelboards, property managers outfitting multi-tenant spaces, or homeowners performing safe, code-compliant circuit protection upgrades in residential or light commercial settings.

Use cases and scenarios:

• Replacing a failing 2-pole breaker in an existing Square D panelboard or load center with a plug-in unit.
• Upgrading a branch circuit to support higher-demand loads (up to 40A) while preserving panel compatibility.
• Specifying a reliable, code-compliant protection solution for new or retrofitted electrical rooms in light commercial environments.

Practical installation tips:

• Verify that your panelboard is compatible with Square D plug-in molded case breakers in the BGA family to ensure proper fit and listing.
• Power down the panel and follow standard safety procedures before replacement or installation.
• Seat the breaker firmly into the bus slot to ensure a solid electrical and mechanical connection for reliable protection.
• Label the circuit clearly after installation to reflect the 40A, 2-pole protection and the specific branch served.
