Westinghouse HQNP3050 - 50A, 3-Pole, Circuit Breaker

Meet the Westinghouse HQNP3050 – a 50A, 3-Pole circuit breaker engineered for dependable overcurrent protection in multi-line electrical systems. Designed for panelboards, switchboards, and control panels, this unit supports three-phase loads with a compact, rugged build that stands up to demanding environments.

Why this 3-Pole breaker stands out

• Three-pole protection for 3-phase systems: Safeguards all three hot conductors in a single device, delivering coordinated protection for motors and other three-phase equipment.
• 50-amp rating: Precisely sized to protect mid-range three-phase loads in distribution panels, reducing the risk of nuisance trips while preserving equipment longevity.
• Versatile installation: Ideal for industrial, commercial, and OEM applications; compatible with panelboards, switchboards, and motor control centers where reliable overcurrent protection matters.
• Easy integration: Designed for straightforward drop-in installation within standard panel infrastructure, simplifying upgrades, expansions, or retrofits.
• Durable, field-ready performance: Built to maintain consistent protection in demanding environments, helping minimize downtime and improve overall electrical safety.

Who benefits from the HQNP3050? Maintenance teams upgrading three-phase motor circuits, system integrators assembling MCCs or distribution panels, and OEM equipment builders requiring a robust three-phase protection solution up to 50A.

Practical use cases

• Three-phase motors in manufacturing lines, conveyors, and processing equipment
• HVAC compressors, pumps, and circulating systems in commercial facilities
• Motor control centers (MCCs) and distribution panels in industrial environments
• OEM assemblies needing reliable protection for three-phase power up to 50A

Compared to single-pole or lower-capacity devices, the HQNP3050 consolidates three-phase protection into one compact, easy-to-wire unit. It’s an effective, straightforward upgrade for new installations or panel refurbishments where precise 50A, three-pole protection is essential.
