Industrial DA3300XZ 300A 3-Pole 240 V Circuit Breaker

Engineered for demanding industrial environments, the DA3300XZ 300A 3-Pole 240 V Circuit Breaker delivers dependable overcurrent protection for three-phase power systems. Identified by Part Number DA3300XZ, this rugged industrial breaker is built to safeguard motors, drives, and distribution panels in manufacturing, processing, and heavy-duty facilities.

Key specifications and what they mean for you

• Current rating: 300 A — designed to protect high-load feeders and large motors without nuisance tripping, helping minimize downtime.
• Poles: 3 — provides full protection for all three phases in a 3-phase distribution system, ensuring simultaneous disconnection for safer, more reliable shutdowns.
• Voltage rating: 240 V — suitable for standard industrial 3-phase power distribution common in many facilities.
• Part Number: DA3300XZ — precise identification for replacement, service, and compatibility with existing switchgear and panels.

Why this 3-Pole, 240 V solution is a smart choice for your plant

• Complete phase protection with a three-pole design ensures all live conductors disconnect together, enhancing safety during faults and maintenance.
• Robust suitability for industrial panels— compact enough to fit within standard enclosures while delivering the protection performance required by busy production lines.
• Direct applicability to large-load circuits such as motor feeders, conveyors, pumps, and HVAC systems, helping to protect expensive equipment and reduce unexpected outages.
• Replacement-ready with the DA3300XZ part number, making upgrades or swaps straightforward in existing installations without re-engineering your panel setup.

Use cases and ideal applications

• Feed protection for heavy machinery and three-phase motors in manufacturing floors, warehouses, and processing plants.
• Upgrade or replacement in legacy switchgear where a 300 A, 3-pole, 240 V breaker is required to restore reliable protection.
• Primary protection for distribution panels serving multiple motor starters, drives, and automation equipment.

Practical guidance for installation and lifecycle

• Verify that your system’s current and voltage requirements align with the 300 A and 240 V rating before installation.
• Ensure compatible mounting within your current panel or MCC to maintain proper clearances and accessibility for maintenance.
• Treat this device as a critical component of your protective scheme—pair it with appropriate upstream and downstream protection to minimize fault propagation and equipment damage.

For facilities relying on stable, three-phase power, the DA3300XZ 300A 3-Pole 240 V Circuit Breaker provides targeted protection with a clear, replaceable identity (Part Number DA3300XZ).
