What does the "VH" stand for in the QOB215VH part number?
The "VH" indicates a Very High interrupting rating. The QOB215VH is rated for 22kAIC at 120/240VAC, whereas a standard QOB215 is rated for 10kAIC.

Does the QOB215VH feature a Visi-Trip indicator?
Yes, this breaker includes a Visi-Trip indicator. When the breaker trips, a highly visible red flag appears in the window to help you quickly identify the faulted circuit in a crowded panelboard.
How does the QOB215VH connect to the panelboard bus?
The QOB215VH uses a bolt-on connection. It features a built-in mounting screw that physically bolts the breaker directly to the panelboard bus bar, providing a secure, vibration-resistant connection for commercial and industrial applications.
