HMA3150 | Circuit Breaker | 150A | 3-Pole | 600V

Meet the HMA3150, a robust industrial circuit breaker engineered for reliability in demanding electrical environments. With a 150-amp rating, a 3-pole configuration, and a 600-volt operating capacity, this unit delivers dependable protection for three-phase feeders and downstream equipment against overloads and short circuits.

Designed for maintenance, retrofit, and replacement projects, the HMA3150 provides a straightforward path to restoring safe, code-compliant protection where exact specifications matter. When sourcing replacements or upgrades, the part number is your best compatibility reference: HMA3150.

Key specifications

• Amperage: 150A
• Pole configuration: 3-Pole
• Voltage rating: 600V
• Type: Industrial circuit breaker

Why this breaker stands out

• 3-Pole design ensures simultaneous protection of all three phases, helping prevent uneven loading and equipment damage in three-phase systems.
• 600V rating makes it suitable for industrial distribution panels, motor feeders, and switchgear operating at higher voltages.
• Clear compatibility reference with the HMA3150 part number reduces guesswork during sourcing for retrofit or replacement projects.

Fitment and compatibility

Before ordering, verify that your system matches the HMA3150 specifications. The part number is the most reliable reference for compatibility, so cross-check it against your panel documentation and equipment ratings.

Ideal use cases

• Maintenance and repair on legacy panels that employ 600V, 150A, 3-pole breakers
• Retrofits to upgrade existing circuits while maintaining three-phase protection and current rating
• Replacement in production environments, industrial automation, and machinery rooms requiring sturdy, industry-grade protection

Practical tips

• Do not assume compatibility—confirm the exact part number (HMA3150) to ensure a proper fit with your enclosure.
• Consider future needs: assess whether your system might demand different current or pole configurations down the line.
• Store breakers in a clean, dry environment to preserve contact reliability and long-term performance.
