The Application Scenarios of GV3 MPCB Miniature Leakage Circuit Breakers

GV3 Motor protection Circuit breaker MPCB

The GV3 Motor Protection Circuit Breaker (MPCB ) is primarily designed for 3-phase motor protection in industrial and electrical systems.

Its key applications include:

1. Motor Protection Systems

Industrial Motors: Protects 3-phase AC motors in machinery from overloads, short circuits, and phase failures. Models like GV3-M06 to GV3-M80 cover current ranges from 0.1A to 80A.
Motor Starters/Controllers: Integrated into motor starter assemblies (e.g., with contactors like CJX2) to provide combined switching and protection .

2. Electrical Distribution Equipment

Control Panels: This equipment is used to ensure the safe operation of the plant power system and supports the normal operation of various types of circuit protection devices and power distribution units.
HVAC Systems: Safeguards compressors, fans, and pumps in heating, ventilation, and air conditioning units.

3. Industrial Machinery

Pumps/Compressors: The device can reliably ensure the normal operation of water pumps and power equipment in various fluid machinery.
Conveyors/Machine Tools: Effectively maintain the safety of automation equipment and transportation machinery in factory production lines during operation.

4. Renewable Energy Systems

Compatible with DC applications (e.g., solar PV systems) up to 600V, protecting inverters and DC motors.

Key Features Enabling These Applications:

Adjustable Thermal Overload Protection: Prevents motor burnout from excessive current.
3-Pole Design: Optimized for 3-phase power systems.
Din Rail Mounting: Facilitates easy installation in control cabinets.
