Cutler-Hammer | MDLB3600 | Circuit Breaker | 600A | 3-Pole | 600V

Introducing the Cutler-Hammer MDLB3600 Circuit Breaker—a rugged, 3-pole protection device engineered for demanding electrical systems. With a 600A amperage rating and a 600V maximum voltage, this breaker is built to safeguard large motor loads and distribution panels in industrial environments. Designed for maintenance, retrofit, and replacement projects where exact specs matter, the MDLB3600 provides a reliable upgrade path when you need seamless compatibility with existing Cutler-Hammer installations.

Key specifications

• Amperage: 600A
• Poles: 3-Pole
• Voltage: 600V

Note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Why choose the MDLB3600

• Three-pole configuration provides synchronized protection across all phases, essential for balanced, safe operation of three-phase equipment.
• High 600A capacity supports heavy electrical loads while remaining within the tested Cutler-Hammer design parameters.
• 600V rating makes it suitable for standard industrial distribution panels and motor control centers that operate at medium voltages.
• Specifically designed for maintenance, retrofit, and replacement tasks where matching your existing part number is critical.

Ideal use cases

• Retrofits of aging panels where a like-for-like MDLB3600 is required to maintain system compatibility.
• Maintenance scenarios where in-field spares ensure minimal downtime for large equipment and motor circuits.
• Replacement of failed breakers in Cutler-Hammer-equipped panels, ensuring consistent trip characteristics and coordination.

How to verify compatibility

Since this is a precise part-numbered device, use the MDLB3600 as the primary reference when checking compatibility with your panel. If your documentation indicates a 3-Pole, 600A, 600V Cutler-Hammer breaker, this model is designed to fit accordingly. Always confirm with your panel’s documentation or a qualified electrician before ordering to avoid mismatches.
