What is the adjustable current range of the GV3-ME63?

The GV3-ME63 has an adjustable thermal overload trip setting from 40A to 63A, allowing customization for different motor protection requirements.

What standards does this breaker comply with?

The GV3-ME63 complies with IEC 60947-2, the international standard for low-voltage switchgear and control gear for industrial use.

Is the GV3-ME63 suitable for three-phase motors?

Yes, the GV3-ME63 is designed specifically for three-phase AC motors with voltages up to 440V AC at 50/60Hz.

What is the breaking capacity of this circuit breaker?

The GV3-ME63 has a breaking capacity of 100kA, providing robust short-circuit protection in industrial environments.

How is the GV3-ME63 mounted?

It can be mounted on DIN rail or directly into control panel enclosures, offering flexible installation options for motor starter panels.

What is Class 10 trip response?

Class 10 means the breaker provides fast response to fault conditions, tripping within 10 seconds under specified overload conditions.

Can this breaker be used as a main disconnect?

The GV3-ME63 is primarily designed for motor circuit protection; consult Schneider documentation for specific disconnect applications.

What makes the GV3 series different from older motor protection devices?

The GV3 series offers improved trip-free operation, faster response times, and better integration with modern motor control systems compared to legacy devices.
