Schneider Electric GVAU207 Undervoltage Release Accessory

Product Description

The SCHNEIDER ELECTRIC GVAU207 is an undervoltage release accessory designed for use with compatible GV-series and TeSys motor circuit breakers. This component monitors supply voltage and triggers a trip action when voltage drops below a set threshold, protecting motors and downstream equipment from running in a low-voltage condition. It mounts directly to the host circuit breaker without additional hardware. Installation is performed by licensed electricians or qualified industrial maintenance technicians working on motor protection panels and control enclosures. The GVAU207 measures 3.6 inches in length, 3.3 inches in width, and 1.4 inches in height, and weighs 0.26 pounds.

The GVAU207 is suited for industrial and commercial electrical installations where motor protection is critical. It is commonly installed in motor control centers, machine control panels, and process equipment enclosures. The accessory adds automatic undervoltage trip functionality to the host breaker, preventing automatic motor restart after a power interruption — an important safety requirement in many industrial applications. It ships as a single unit and is intended as a direct snap-on accessory for the supported breaker families listed below.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and the manufacturer's wiring diagrams. De-energize and lock out the circuit before attaching or removing the accessory from the host breaker. Verify voltage rating compatibility between the GVAU207 and the supply circuit before commissioning. Do not operate the host breaker with the accessory partially seated.
