Square D QOM100VH8106 100A 2-Pole 100 V Circuit Breaker Potential Transformer

Meet the Square D QOM100VH8106, a purpose-built circuit breaker designed to deliver dependable overcurrent protection in electrical distribution systems. With a 100 A current rating and a compact 2-pole configuration, this unit secures both conductors in a single operation, helping protect wiring, devices, and downstream equipment from overloads and short circuits. Its 100 V rating makes it suitable for controlled low-voltage applications where precise interruption is essential.

This model belongs to Square D’s QOM family, cleanly integrating into panels that support QOM-type breakers. The built-in potential transformer compatibility (as suggested by the model name) provides options for metering and monitoring configurations, making it a thoughtful choice for installations that require measurement-driven protection alongside reliable shutoff capability.

• Part Number: QOM100VH8106
• Current rating: 100 A
• Poles: 2
• Voltage rating: 100 V
• Series: Square D QOM family
• Application: Protective device for feeders and circuits in panels designed for QOM breakers, with potential transformer compatibility for metering-focused setups

Who benefits from the QOM100VH8106? electricians and facilities teams replacing or stocking spare breakers for Square D panels, technicians configuring low-voltage distribution with precise measurement requirements, and any install requiring reliable two-pole protection at a 100 A level. It’s well-suited for panel boards and distribution boxes where quick, synchronous disconnection of both lines is critical for safety and equipment longevity.

Practical usage notes: verify that your panel accepts QOM-type breakers, ensure the voltage rating matches your system, and follow proper lockout/tagout procedures during replacement. This breaker is intended for professional installation and should be handled by qualified personnel to maintain system integrity and safety.
