EDB34080SA - 80 Amp Circuit Breaker w/ Shunt Trip

EDB34080SA - 80 Amp Circuit Breaker w/ Shunt Trip

The EDB34080SA miniature circuit breaker is designed to deliver dependable electrical protection with a form, fit, and function that aligns with commercial and industrial panelboard requirements. Engineered for use in legacy and current NF panelboard systems, this 3‑pole breaker is rated for 80 amps at up to 480Y/277VAC, making it suitable for a wide range of applications where secure short‑circuit and overload protection is essential. Whether in new installations or as a direct replacement for existing components, the EDB34080SA supports electrical safety and system continuity with features that help simplify installation and maintenance.

Key Features and Benefits

• Circuit Protection You Can Install Confidently: Provides short‑circuit and overload protection to safeguard circuits against damage while meeting standard electrical requirements.
• Shunt Trip Capability: Includes an integrated shunt trip unit, giving users the ability to remotely trip the breaker when required for safety or control.
• Thermal‑Magnetic Trip Unit Technology: Combines thermal and magnetic trip elements for response to both prolonged overloads and instantaneous fault currents.
• Clear Trip Signaling: Built‑in local trip indicator helps technicians quickly identify a tripped breaker during maintenance checks.
• Bolt‑On Mounting: Easy to secure into compatible NF panelboards with a bolt‑on design, offering physical stability in electrical enclosures.
• Wide Conductor Support: Accepts a range of aluminium and copper wire gauges — from AWG 12 up to 2/0 — simplifying installation with common conductor sizes.

Where It Works Best

• This 80A EDB miniature circuit breaker is ideal for commercial or industrial electrical panels where reliable protective devices are required. It fits NF panelboards that accept E‑Frame miniature breakers and is particularly useful when replacing or matching existing breakers in legacy installations. The shunt trip feature makes it a strong candidate for systems that need remote disconnect capability — such as controlled power shutdowns for safety or maintenance purposes.
