Square D EDB34080SA - 80 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Square D EDB34080SA is an 80 A, 3-pole bolt-on molded case circuit breaker designed to safeguard panelboards and load centers from overcurrent and short circuits. Built for dependable protection in residential, commercial, and light industrial settings, this breaker is a robust choice for reliable electrical distribution.

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection that stays put even in panels exposed to vibration or door movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection—fast enough to interrupt short circuits and gentle enough to avoid nuisance trips during normal startup surges. This helps protect wiring and devices while reducing maintenance calls.
• OEM-compatible with matching Square D load centers and panelboards to ensure a clean fit and a UL-listed installation.
• Three-pole design suitable for three-phase circuits commonly found in commercial and light industrial applications.
• 80A rating supports higher-capacity feeders and branch circuits, enabling efficient distribution for mid-size electrical layouts.
• Molded-case construction offers durable insulation and a compact footprint designed to fit standard Square D panel enclosures.

Technical details at a glance:

• Manufacturer: Square D
• Part number: EDB34080SA
• Type: Thermal-magnetic molded case circuit breaker
• Amperage rating: 80 A
• Number of poles: 3
• Mounting style: Bolt-on

Use cases and scenarios:

• Replacing a worn or tripped breaker in compatible Square D panelboards, ensuring you maintain proper protection across critical feeders.
• Providing robust protection for 3-phase circuits in light commercial spaces, such as small offices, workshops, or retail environments that rely on reliable equipment protection.
• Upgrading distribution feeders to 80 A in a multi-cubicle panel where higher current protection is needed without changing the existing panel layout.

Why choose the EDB34080SA in your electrical setup? It combines a secure bolt-on installation with a precise thermal-magnetic trip characteristic that you can count on to maintain system integrity under typical load conditions and in fault events. When compatibility with Square D panels is essential, this unit slides into place as a drop-in replacement that preserves panel balance and protection coordination.

Practical tips for value and longevity:

• Verify your panelboard accepts bolt-on breakers from the EDB family before installation. The fit and alignment of the bus connection are key to reliable operation.
• Coordinate with upstream protective devices to ensure proper selective coordination, reducing the likelihood of wider outages during faults.
• During installation, handle with care and ensure the panel is de-energized and de-pressurized per standard safety practices before replacement or retrofitting.
