Square D EDB24080 - 80 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Square D EDB24080 is an 80 A, 480 V, 2-pole bolt-on molded case circuit breaker designed to deliver reliable branch-circuit protection in panelboards and load centers. Built for demanding commercial and light industrial environments, this device safeguards critical electrical distributions with precise overcurrent and short-circuit protection.

Key advantages that set this breaker apart:

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection, reducing contact issues and ensuring long-term reliability in panels subject to vibration or heavy loading.
• Thermal-magnetic trip unit combines steady thermal overload protection with an instantaneous magnetic trip for high fault currents, delivering stable, repeatable protection performance.
• OEM-compatible design matches Square D panelboards and load centers that accept bolt-on molded case breakers, simplifying retrofits and ensuring safe, compliant installations.
• Versatile for multiple applications suitable for residential, commercial, and light industrial settings where dependable 480 V distribution is essential.

How it solves real-world problems:

• In retrofit projects, bolt-on mounting minimizes panel disruption and maintains a secure bus connection even in vibration-prone environments, supporting long-term reliability.
• The thermal-magnetic protection curve provides predictable trips, reducing nuisance interruptions from normal load fluctuations while still delivering rapid response during short circuits.
• With an 80 A rating at 480 V and two poles, it protections both conductors of a branch circuit, ensuring simultaneous disconnection for enhanced safety.
