• Voltage rating: 240VAC
• Poles: 3-Pole
• Breaker type: Circuit Breaker

Why this 3-Pole design matters

The 3-Pole configuration provides balanced protection across all three phases, making it ideal for three-phase distribution and motor circuits. By safeguarding each leg of the power trio, it helps prevent phase imbalance and common-mode faults from cascading into equipment damage or unexpected downtime.

Ideal applications

• Protection for three-phase motor circuits and feeders in industrial facilities
• Distribution panelboards, switchboards, and control panels in commercial settings
• OEM equipment protection where compact, reliable overcurrent protection is required

What makes it stand out

Designed for durability and compatibility with Gould panel environments, the BQ3-B040 delivers robust overcurrent protection without sacrificing ease of integration. Its 240V capacity covers common industrial feeders, while the 40A rating aligns with typical motor and line contingencies—helping you prevent nuisance trips and extend equipment life.

Practical considerations

• Verify compatibility with your panelboard or switchboard layout to ensure proper fit and electrical clearances
• Follow standard installation practices for three-phase circuits, including appropriate conductor sizing and secure terminations
• Regularly inspect for signs of wear or exposure to harsh conditions, and replace if the unit shows damage or aging components

Equip your distribution panels and motor control centers with the Gould BQ3-B040 to deliver reliable, three-phase protection that keeps systems running smoothly.
