Purchase now: Schneider Electric GV2ME08 Motor Breaker
Purchase now: Atlantech Drives provides you the Schneider Electric GV2ME08, a reliable and compact **Motor Protective Circuit Breaker** from the world-famous **TeSys GV2** range. This unit is calibrated for smaller industrial motors, offering a thermal adjustment range of **2.5 A to 4 A**. It is perfectly suited for protecting 3-phase asynchronous motors rated around **1.1 kW to 1.5 kW** (at 400V), commonly found in small conveyor belts, dosing pumps, and extraction fans.
Technical Specifications and Class 10 Protection
The GV2ME08 provides **Class 10** thermal overload protection, meaning it will trip within 10 seconds at 7.2 times the set current (locked rotor condition), preventing motor burnout. It combines this with instantaneous magnetic short-circuit protection. The unit is extremely compact (45mm width) and allows for the side-mounting of auxiliary contact blocks (GVAE, GVAN) to signal the trip status to a PLC or pilot light.

Expert Installation Advice: Setting the Dial
Setting the current accurately is vital. Expert Tip: Always set the yellow dial exactly to the motor’s **Full Load Amps (FLA)** or Nominal Current (In) shown on the motor nameplate, NOT the Service Factor Amps. The GV2ME08 has built-in temperature compensation, so there is no need to «add 10%» for safety. Setting it too high defeats the purpose; setting it too low causes nuisance tripping during startup.
Frequently Asked Questions (FAQs)
Q: Does this unit have «Phase Loss Sensitivity»?
A: Yes, the GV2ME series includes differential monitoring. If one phase is lost (e.g., a blown fuse upstream), the mechanism accelerates the tripping to prevent the motor from single-phasing and burning out.
Q: What is the breaking capacity at this low amperage?
A: At the 2.5-4A range, the GV2ME08 is rated for **100 kA** (Icu) at 400V, meaning it is effectively self-protected against almost any short circuit current in a standard panel without needing back-up fuses.
