Schneider Electric | HDL36020LU | Circuit Breaker | 20A | 3-Pole | 600V

The Schneider Electric HDL36020LU Circuit Breaker is a purpose-built protection device designed for reliable performance in three‑phase electrical systems. With a 20A rating across 3 poles and a voltage threshold of up to 600V, this breaker is ready for demanding commercial and industrial panel applications where precise compatibility matters.

• Amperage: 20A
• Poles: 3-Pole
• Voltage: 600V
• Reference part number: HDL36020LU (best compatibility reference)

Why this matters in real-world setups: a 3‑pole design protects all three conductors in a three‑phase system, allowing for coordinated disconnection during faults and safer maintenance. The HDL36020LU is engineered to fit panels that require this specific configuration, helping you maintain electrical protection without the need for awkward adapters or workarounds.

This breaker is ideal for:

• Maintenance projects where existing panels need a direct, reliable replacement
• Retrofits that expand or modernize three‑phase distributions
• Replace-and-upgrade scenarios where the HDL36020LU matches the panel’s original specifications

Important compatibility note: confirm fit and ratings before ordering. The HDL36020LU is the best reference for ensuring a seamless match with your panel or distribution board. If your project relies on exact part references, using this HDL36020LU part helps maintain the intended protection profile and trip characteristics.

Practical guidance for installation and use:

• Verify that your panel is rated to accept a 3‑pole 20A, 600V device and that the physical dimensions align with the enclosure’s bus and mounting specifications.
• Before replacing an existing breaker, compare the catalog or panel labeling to the HDL36020LU to ensure full compatibility and desired trip curve.
• Plan for safe, professional handling during replacement to maintain system integrity and compliance with applicable electrical codes.

Choosing the HDL36020LU means aligning with Schneider Electric’s established protection philosophy for three‑phase circuits, delivering predictable performance, straightforward procurement through part-number accuracy, and a reliable path to keep your electrical system protected during routine maintenance and panel upgrades.
