Industrial QP3B015 15A 3-Pole 240 V Circuit Breaker Potential Transformer

Industrial QP3B015 15A 3-Pole 240 V Circuit Breaker is built for reliability in demanding electrical environments. With a 15-amp current rating, three poles, and a 240-volt rating, this part (QP3B015) delivers synchronized protection across all three phases for motor loads, feeders, and distribution circuits in your facility.

Key specifications

• Current rating: 15 A
• Poles: 3
• Voltage rating: 240 V
• Part number: QP3B015

Why this 3‑pole design matters

• Comprehensive three-phase protection: By interrupting all three phases simultaneously, it prevents phase-to-phase faults from leaving equipment partially energized, which can help protect motors and drives from damage.
• Consistent performance in industrial environments: Built to withstand the rigors of manufacturing floors and power-distribution panels where reliable protection matters most.
• Efficient integration: Designed to fit into standard industrial panels, simplifying upgrades and retrofits for existing 3‑phase circuits.

Ideal use cases

• Protecting three-phase motors in conveyors, pumps, fans, and CNC equipment
• Safeguarding feeders and branch circuits in power distribution panels
• Upgrading control panels in manufacturing facilities and industrial HVAC systems

How it solves real-world challenges

• Quick interruption of fault currents reduces the risk of collateral damage to wiring and components, helping keep production lines running.
• Precise load protection: The 15 A rating aligns with typical three-phase loads, providing targeted protection without unnecessary trips for normal starting currents.
• Long-term reliability: Built for continuous operation in harsh environments, delivering consistent performance across shifts and seasons.

Practical tips for selecting and installing

• Confirm your system is a 240 V, three-phase setup to match the 3-Pole, 240 V specification.
• Match the current rating to the load profile, ensuring loads operate well within the 15 A limit to avoid nuisance trips.
• Plan for modular integration in compatible panels, and verify mounting and wiring practices align with your panel manufacturer’s guidelines.
• Consider future expansion to slightly higher current ratings if you anticipate motor or feeder upgrades, keeping protection aligned with actual load demands.

With the Industrial QP3B015, you gain dependable three-phase protection that supports safer, more efficient electrical distribution in industrial settings. It’s the smart choice for teams upgrading control panels and safeguarding critical equipment across manufacturing floors.
