Square D EGB14020 - 20 A, 277 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D EGB14020 — a rugged, single-pole, 20A bolt-on molded case circuit breaker designed for dependable branch-circuit protection in panelboards and loadcenters. With a thermal-magnetic trip unit and secure bolt-on mounting, it delivers precise protection and reliable performance in challenging commercial and light-industrial environments, while staying compatible with your OEM equipment.

Why this breaker stands out

The EGB14020 uses a bolt-on design that creates a rigid, vibration-resistant bus connection, reducing the risk of loose connections and heat buildup in high-use panels. The thermal-magnetic trip mechanism provides stable, repeatable protection against both overloads and short circuits, even as ambient conditions change. Built to work with matching OEM loadcenters and panelboards, it installs quickly and integrates cleanly into existing electrical infrastructure without adapters or workarounds.

Key benefits

• Rigid, vibration-resistant mounting: bolt-on connection minimizes movement and arcing, improving long-term reliability in busy electrical rooms.
• Thermal-magnetic protection: combines current-based and fault-based tripping for accurate, dependable safety against overloads and short circuits.
• OEM-compatible design: guaranteed fit with matching loadcenters and panelboards for a seamless upgrade or replacement.
• Versatile application: ideal for residential, commercial, and light-industrial circuits powered by 277V systems.
