Industrial QBHW2080H 80A 2-Pole 240 V Circuit Breaker Potential Transformer

Meet the Industrial QBHW2080H 80A 2-Pole 240 V Circuit Breaker Potential Transformer—a rugged protection device engineered for demanding industrial power systems. With an 80-amp current rating and a two-pole design, it interrupts both hot lines in a 240-volt circuit, delivering synchronized protection across the system.

This model is a robust solution for protecting motors, feeders, and heavy equipment in manufacturing facilities, data centers, and utility rooms. Its resistance to vibration and thermal cycling helps reduce nuisance trips and downtime in harsh environments.

What sets the QBHW2080H apart

• 80 A current rating designed to handle high-load circuits common in industrial settings without compromising protection.
• 2-Pole, 240 V configuration ensures complete circuit shutdown on fault conditions, safeguarding both conductors and connected equipment.
• Industrial-grade reliability built to perform consistently under demanding conditions typical of production floors and switchgear rooms.
• Clear part identification Part Number QBHW2080H simplifies sourcing, replacement, and inventory management in busy maintenance environments.
• Potential transformer compatibility (as part of protection and metering schemes in industrial power systems), enabling streamlined integration with measurement and control workflows.

Ideal use cases

• Motor control centers and panel boards where 240 V feeders require dependable overload and short-circuit protection.
• Crucial line feeders in manufacturing lines, conveyors, presses, and heavy machinery.
• Electrical rooms and data centers that rely on robust, maintenance-friendly protective devices.

Why this matters for your operation

Choosing the QBHW2080H means aligning protection with real-world loads. An 80-amp rating matches typical industrial feeders, while a two-pole design ensures a coordinated trip across both lines, reducing the risk of partial faults and electrical arcing. The result is lower downtime, safer operation, and a more predictable maintenance footprint.

Practical tips for install and care

• Always follow manufacturer installation instructions and torque specifications for lugs and mounting hardware.
• Verify compatibility with your panel, bus configuration, and any metering or protection schemes in use.
• Inspect connections for tightness during routine maintenance to prevent thermal buildup and intermittent trips.

For reliable, industrial-grade protection on 240 V circuits, the QBHW2080H 80A 2-Pole Circuit Breaker is a clear choice. Integrates seamlessly into systems that demand rugged protection, straightforward sourcing, and dependable performance over the long term.
