Square D EDB36020 - 20 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D EDB36020—a 3‑pole, 20A, 600V molded case circuit breaker built for dependable branch circuit protection in panelboards and load centers. With secure bolt‑on mounting and a rugged bus connection, it stays firmly in place even in demanding installations, delivering reliable performance when it matters most.

Why this breaker stands out

• Secure bolt‑on mounting: Provides a rigid, vibration‑resistant connection to the bus, reducing loose contacts and improving long‑term reliability.
• Thermal‑magnetic trip unit: Combines temperature‑based overload protection with fast magnetic short‑circuit protection for stable, repeatable responses across varying loads and conditions.
• Specifically matched for OEM panels: Designed to be compatible with the corresponding Square D OEM load centers and panelboards, ensuring proper fit and coordinated protection.
• Versatile across environments: Suitable for residential, commercial, and light industrial applications where robust branch‑circuit protection is needed.

Ideal use cases

• Protect horizontal and vertical branch circuits in new installations or panelboard upgrades within homes, offices, and small retail spaces.
• Upgrade or retrofit existing Square D panelboards where a 3‑pole, 20A, 600V protection device is required for 3‑phase systems or multi‑breaker configurations.
• Distribute power safely to equipment and circuits in mechanical rooms, workshops, and light industrial environments where vibration resistance and reliable trip performance matter.

What problems it solves

When a branch circuit overloaded or a short circuit occurs, the EDB36020 reacts quickly to interrupt current, helping prevent damage to wiring, devices, and downstream equipment. The thermal element handles gradual temperature rises, while the magnetic element snaps into action during high‑energy faults, delivering predictable protection in variable conditions. Its bolt‑on design minimizes connection stress over time, helping maintain consistent protection across the life of the installation.

Compatibility and installation notes

Designed to work with matching OEM load centers and panelboards, the EDB36020 simplifies selection and replacement by aligning with your existing Square D ecosystem. Its bolt‑on mounting is ideal for installations where a secure, vibration‑resistant connection is critical, such as in spaces with equipment noise, movement, or mounting challenges. When installing, inspect bus connections and torque requirements per standard electrical practices to maximize reliability.
