Information About QOB3110VH

The QOB3110VH is a molded case circuit breaker within the QO Series, specifically engineered to provide reliable overcurrent protection in a variety of electrical systems. Designed for applications demanding robust circuit protection, this breaker is rated for 120/240 VAC and accommodates currents up to 110 A. This makes it ideal for both commercial and light industrial environments where uninterrupted power and equipment safety are paramount.

A key feature of the QOB3110VH is its bolt-on mounting style, ensuring secure attachment and stable installation in panelboards and load centers. This mounting method enhances its suitability for fixed installations, providing resistance to vibration and reducing the risk of loosening over time. As a 3-pole breaker, the QOB3110VH can interrupt currents across three phases, making it compatible with three-phase systems, commonly used in industrial and commercial facilities requiring balanced load distribution and efficient power management.

This circuit breaker’s molded case construction is designed to withstand high levels of mechanical stress and environmental challenges, providing durability and stability under heavy-duty usage. The molded case encapsulates and protects the internal components, minimizing the exposure to dust, moisture, and contaminants that could otherwise impact performance. This enclosure style also contributes to enhanced thermal management, allowing the breaker to handle rated currents without overheating, which is essential in prolonged and high-load applications.

In terms of operational functionality, the QOB3110VH offers precise overcurrent protection, automatically disconnecting the circuit in cases of overload or short-circuit events. This response helps to prevent potential damage to connected equipment and wiring, ensuring operational safety while minimizing the risk of costly downtime. Its thermal-magnetic tripping mechanism provides dual protection: thermal sensing for long-duration overloads and magnetic tripping for instant response to high current surges, effectively covering a range of fault conditions within electrical systems.
