Schneider Electric | MP20-3P-DO-CRADLE | Circuit Breaker | 20A | 3-Pole

Schneider Electric MP20-3P-DO-CRADLE is a 20A, 3-Pole circuit breaker built for maintenance, retrofit, and replacement projects where exact specs matter. This OEM component delivers reliable protection within compatible MP20-series enclosures and features a cradle mounting design that simplifies installation in supported panels.

Why this particular MP20-3P-DO-CRADLE stands apart:

• Exact compatibility: Use the MP20-3P-DO-CRADLE part number as your primary reference to ensure you’re selecting the correct 3-pole, 20A protection for your system. Always confirm fit and ratings before ordering.
• Three-pole protection: A true 3-Pole design delivers coordinated interruption across three conductors, ideal for three-phase systems and balanced protection.
• Cradle mounting for quick installs: The cradle configuration enables fast mounting and removal in suitable enclosures, reducing downtime during maintenance and retrofits.
• OEM Schneider Electric reliability: Built to align with Schneider Electric’s protection standards, offering consistent performance and compatibility with related breakers and panels.

Who should consider this part:

• Electrical contractors performing panel retrofits or replacements in three-phase environments.
• Facilities maintenance teams maintaining industrial control panels, service entrances, or manufacturing lines that require a 20A triple-pole protector.
• Maintenance fleets that keep genuine Schneider Electric parts on hand to minimize mismatches and long lead times.

Practical use scenarios:

• Replacing a worn or failed 3-Pole 20A breaker within an MP20-series enclosure without modifying the panel interior.
• Standardizing 3-phase protection across multiple circuits with the same part number to simplify stocking and service checks.
• Preparing for a retrofit where a 3-pole 20A solution is the appropriate protection level for a newly wired machine or process line.

Important compatibility notes:

• Part number MP20-3P-DO-CRADLE is the best reference for compatibility with matching enclosures and ratings.
• Always verify the panel model, enclosure type, and incoming supply configuration to ensure a correct match.

Installation and safety tips:

• Power down the equipment and lockout/tagout the circuit before inspecting or replacing breakers.
• Verify that the device’s rating (20A, 3-Pole) matches the circuit requirements, and ensure the enclosure supports a cradle-type mounting.
• Consult the enclosure’s documentation for any manufacturer-specific installation steps or torque specs, and use proper tools to seat the breaker securely.
