Square D EDB34030 - 30 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D EDB34030 — a 30 A, 480 V, 3-pole bolt-on molded‑case circuit breaker designed to deliver reliable branch circuit overcurrent and short‑circuit protection in panelboards and load centers. Built for steady performance in demanding environments, it pairs a rugged bolt‑on mounting with a precise thermal‑magnetic trip system to keep electrical systems safe and uptime high.

Key benefits that set this breaker apart:

• Secure bolt-on mounting creates a rigid, vibration‑resistant bus connection, reducing movement and arcing risk in panels subjected to equipment vibration or dynamic loads.
• Thermal‑magnetic trip unit provides stable, repeatable protection by combining a temperature‑compensated thermal element with a fast magnetic trip for instantaneous short‑circuit response.
• 3‑pole, 30 A, 480 V configuration is tailored for 3‑phase distribution in commercial and light industrial settings, while staying compatible with existing Square D infrastructure.
• OEM panel compatibility is designed to work with matching Square D panelboards and load centers, simplifying replacements and upgrades with predictable fit and function.
• versatile application suitable for residential, commercial, and light industrial systems that require dependable protection without complicating the panel layout.

Use cases and practical scenarios

• Upgrading a 3‑phase distribution panel in a small industrial facility where 480 V equipment requires robust protection and a durable mounting solution.
• Replacing aging breakers in commercial load centers, where a secure bolt‑on connection helps maintain long‑term reliability in busy electrical rooms.
• Installing a reliable protection device in residential-adjacent or light industrial subpanels that demand consistent performance under varying loads.

Why this Square D breaker is a smart choice for your electrical protection needs: the bolt‑on design minimizes installation complexity and ensures a solid bus connection, while the thermal‑magnetic trip unit delivers predictable, field‑reliable performance across temperatures and fault currents. When paired with the appropriate OEM panelboard, it provides a cohesive, durable protection solution for demanding electrical environments.
