Square D | HDM36060 | Circuit Breaker | 60A | 3-Pole | 600V | 18kA | Bolt-On

The Square D HDM36060 is a bolt-on, three-pole circuit breaker engineered to deliver dependable protection for 60-amp, 600-volt circuits in commercial and light industrial panels. Designed for maintenance, retrofit, and replacement projects, this model ensures you can match the exact Square D specifications your system requires without compromising safety or performance. Key specifications

• Amperage: 60A
• Poles: 3-Pole
• Voltage rating: 600V
• Interrupting capacity: 18kA
• Mounting type: Bolt-On
• Part number: HDM36060

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility, especially when matching to existing Square D bolt-on panels or assemblies.

Use cases and applicability

This breaker is ideal for three-phase feeders and branch circuits that require reliable overcurrent protection in 600V systems. It’s well-suited for:

• Retrofits to upgrade older panels to modern protection standards
• Replacements in Square D bolt-on panel configurations
• New installations where a precise 60A, 3-pole, 600V protection device is needed
• Motor control centers and commercial power distribution where consistent trip characteristics matter

Why this model stands out

• Exact fit for Square D bolt-on panels: The HDM36060 is purpose-built to align with Square D mounting patterns and trip characteristics, reducing compatibility risk.
• Clear, predictable protection: With a dedicated 60A rating and 18kA interrupting capacity, it handles fault currents in typical commercial/industrial environments with confidence.
• Reliability in demanding environments: Designed for repeated operation in systems that demand consistent performance and quick isolation of faults.

Installation and practical guidance

Installing a bolt-on breaker like the HDM36060 should follow standard Square D installation practices and the panel manufacturer’s guidelines. Verify panel compatibility using the part number, ensure the power is fully de-energized before service, and secure the breaker according to the panel’s mounting procedure. If you’re replacing an older device, compare mounting hole alignment and electrical ratings to ensure a seamless swap.

Maintenance and inspection considerations

For long-term reliability, inspect the breaker during routine panel maintenance to confirm the trip mechanism remains clean and unobstructed, and that there are no signs of overheating or physical damage. Keep a record of the replacement part number (HDM36060) for future service needs to preserve consistent protection across your electrical system.

Bottom line

Choose the Square D HDM36060 when your project requires a precise, bolt-on 60A, 3-pole circuit breaker rated for 600V with an 18kA interrupting capacity. It’s a purpose-built solution for maintenance, retrofit, and replacement scenarios where exact compatibility and dependable protection matter most. Remember: the part number is the best reference to guarantee a correct fit and performance in your system.
