SCHNEIDER TeSys ® GV2/GV3 series motor circuit breakers

TeSys ®  The GV2/GV3 series are specialized circuit breakers for electric motors launched by Schneider Electric, including two categories: domestic and imported. They cover two types: thermal magnetic (GV2-ME/PM, GV3-P/ME) and electromagnetic (GV2-LE/L, GV3-L), with a rated current range of 0.1-80 A, suitable for motor power up to 37 kW, rated insulation voltage up to 690 V, and breaking capacity of 3-100 kA. They comply with the IEC 60947 series standard and have overload, short circuit, and phase loss protection functions. They support screw/spring/ring terminal connections and can be matched with auxiliary contacts, undervoltage/shunt release, current limiter and other accessories. The highest protection level is IP65, and the working temperature is -20 ° C~+60 ° C. Widely used in circuit protection scenarios for various industrial motors.
