Information About QOB330VH
The QOB330VH is part of the Square D QO series, a well-established family of miniature molded case circuit breakers used in distribution and control panels. It is constructed with a compact molded case design and an over-center, trip-free toggle mechanism that ensures consistent tripping behavior. The breaker integrates seamlessly with QO-compatible panelboards using bolt-on mounting and pressure plate terminations. It is typically used in lighting, motor, and general-purpose branch circuits where thermal-magnetic protection and visual trip indication are required.
Key Features:
- Three-pole configuration: Supports three-phase or multi-circuit protection.
- Thermal-magnetic trip unit: Provides overload and short-circuit protection.
- Bolt-on mounting: Ensures secure mechanical and electrical connection.
- VisiTrip indicator: Displays a clear visual signal when the breaker trips.
- Trip-free toggle mechanism: Prevents holding the breaker closed during fault conditions.
- HACR rated: Suitable for heating, air conditioning, and refrigeration circuits.
- Compact QO form factor: Optimized for space-efficient panel installations.
The QOB330VH delivers the reliability and precision required for branch circuit overcurrent protection in commercial and industrial electrical systems.
