Schneider Electric GV2ME08 9A-13A is a compact and essential component in industrial motor control and protection. Here is a detailed overview of its features, functions, and typical applications.

Overview and Identity

Product Line: TeSys GV2

Manufacturer: Schneider Electric

Specific Model: GV2ME08

Current Range: 9A to 13A (Adjustable)

Product Type: Motor Circuit Breaker (MCB) or Motor Protection Circuit Breaker (MPCB)

In simple terms, this is a specialized fuse and disconnect switch combined into one unit, designed specifically for the unique demands of electric motors.

Key Features and Functions

Motor Protection:

Short-Circuit Protection (Magnetic): Reacts instantly to high-current faults (like a short circuit), tripping to prevent catastrophic damage to the motor and wiring.

Overload Protection (Thermal): Uses a bimetallic strip that heats and bends with sustained overcurrent (e.g., motor overload). The adjustable dial from 9A to 13A allows you to set the exact trip point to match the Full Load Amps (FLA) of your specific motor.

Isolation Function:

The robust switching mechanism provides a safe and visible means of isolation. When the handle is in the "OFF" position, it physically disconnects the motor from the power source, allowing for safe maintenance. It meets recognized isolation standards.

Trip Class:

GV2 breakers typically come in different trip classes (e.g., Class 10A). A Class 10 trip is standard for most motors, meaning it will trip within 10 seconds at 600% of its set current. This allows for the high inrush current when a motor starts without nuisance tripping, while still providing fast protection under fault conditions.

Manual ON/OFF Control:

The large, clear handle allows for easy manual operation to start or stop the motor locally.

Auxiliary Contacts (as an option/add-on):

You can attach auxiliary contact blocks (e.g., model GV2AF1, GV2AF2) to the side of the breaker. These provide a signal to the control system (like a PLC) to indicate the breaker's status (tripped/on/off).

Undervoltage Release (as an option/add-on):

An accessory coil (e.g., GV2ME02) can be added which will automatically trip the breaker if the control voltage is lost, preventing unexpected automatic restart upon power return (a key safety feature).
