QI-GFCI Circuit Breaker
The WEB QI-GFCI is a hydraulic-magnetic GFCI circuit breaker designed for consistent, code-compliant protection in residential and commercial panels.
A GFCI breaker has one job: detect a ground fault before it becomes a shock hazard and trip the circuit. The WEB QI-GFCI does that at the sensitivity level code requires - 4 to 6 milliamps, Class A-and it does it consistently, regardless of where the panel is or what the temperature is doing.
Most GFCI breakers use bimetallic technology, which means their performance can drift as ambient temperature changes. The WEB QI-GFCI uses hydraulic-magnetic technology instead. That means the same precise tripping characteristics whether the panel is in a heated mechanical room or an uninsulated garage in January.
It also runs a self-test automatically and signals status through an LED indicator. No manual testing, no guesswork, no pulling the breaker to check if it's still doing its job.

Why Installers Prefer It Over the Standard Option:
The standard move is to install GFCI outlets at every required location and call it done. That works - until one trips and nobody can figure out which outlet it was, or a bimetallic breaker starts nuisance-tripping in cold weather because the temperature sensitivity wasn't something anyone thought to check at the spec stage. This QI-GFCI solves those problems at the source.
The QI-GFCI protects the whole circuit from the panel, trips cleanly when it needs to, and tells you it's working without you having to ask. For OEM applications like hot tub and spa panels - where the breaker lives outside, gets ignored for years, and needs to work perfectly when it finally matters - that's not a nice-to-have. It's the right call.
