Eaton BQL315 15A 3-Pole 240 V Circuit Breaker Potential Transformer

Meet the Eaton BQL315, a rugged 3-pole circuit breaker designed for three-phase power systems. With a 15 A current rating and a 240 V tolerance, this unit provides dependable overcurrent protection for demanding commercial and light industrial applications. Built to safeguard equipment and reduce downtime, it helps keep motors, feeders, and controllers operating safely and efficiently.

Why the BQL315 stands out

• Three-pole protection for complete phase isolation — when a fault occurs, all three hot legs disconnect together, preventing unsafe voltages from remaining on the line and enhancing system safety.
• Precise 15 A protection — tailored for circuits that require a clear, reliable current threshold to guard motors, pumps, and distribution feeders from overloads without unnecessary trips.
• 240 V compatibility — ideal for common three-phase power configurations found in many commercial and light industrial environments, ensuring smooth integration with standard electrical infrastructure.
• Compact, robust design — crafted to fit into dense panel layouts while delivering consistent performance in real-world electrical rooms and equipment racks.
• Versatile in protection schemes — suitable for use in systems that employ potential transformers for monitoring and control, helping you align protection with your metering and protection strategy.
