EGB14040 - 40 Amp Circuit Breaker

EGB14040 - 40 Amp Circuit Breaker

The EGB14040 Mini Circuit Breaker from Schneider Electric delivers dependable, high‑performance protection for lighting and low‑voltage panelboards. As a 1‑pole, 40-amp circuit breaker designed for 277 VAC service, this compact bolt‑on E‑Frame unit blends a space‑saving profile with serious protection capability. Inside, a thermal‑magnetic trip unit reacts quickly to overloads or short circuits—giving you consistent safety coverage for lighting loads and other low‑voltage electronics. Whether you’re outfitting a small commercial lighting board or upgrading a residential panel, the EGB14040 offers a reliable, long-lasting solution you can count on.

Key Features and Benefits

• Compact, space‑saving design: The slim E‑Frame form factor installs neatly in standard NF-style panelboards, making it easy to upgrade or expand your lighting circuits without re‑engineering your layout.
• High interrupt capacity: With a breaking capacity of 65 kA at 120 VAC (and 35 kA at 277 VAC), this breaker ensures strong protection against overloads and short circuits—giving your system a dependable safety margin.
• Thermal‑magnetic trip mechanism: Combines both thermal and magnetic trip functions to handle both overload conditions and fault currents quickly and accurately.
• Bolt‑on mount for secure installation: The bolt‑on configuration keeps the breaker firmly in place, reducing the risk of loosening or malfunction over time—ideal for panelboards in busy or vibration-prone environments.
