Motor Circuit Breaker: Overload and Short Circuit Protection for Motors

Motor Circuit Breaker: Overload and Short Circuit Protection for Motors

The motor circuit breaker is a protective device for motor circuits, automatically cutting off power during overload, short circuit, or phase loss faults to protect motors and connected equipment. It combines overcurrent protection and manual switching functions, featuring rapid tripping and reliable operation. Commonly installed in motor control cabinets, pumps, and compressors, this breaker ensures safe motor operation, reduces maintenance costs, and prevents equipment damage from electrical faults.

Advantages

Comprehensive Overload Protection

Combines thermal-magnetic tripping for overloads (1.1-1.5x rated current) and instant short-circuit protection (10x rated current), ensuring motor safety.

Quick-Reset Mechanism

Manual reset within 5 seconds after fault clearing, reducing downtime compared to fuses or traditional circuit breakers.

Phase Loss Detection

Automatically trips when any phase is lost, preventing motor burnout from single-phasing in three-phase systems.

The GV2ME06 from Yueqing Huilong is a compact motor protection breaker designed for small to medium-sized motors, combining overload and short-circuit protection in a single unit. This breaker features an adjustable current setting range (0.1-0.16A), allowing precise customization for motor ratings. The thermal-magnetic tripping mechanism responds to both overloads (thermal) and short circuits (magnetic), with a trip class of 10A for reliable protection. The GV2ME06 fits standard 35mm DIN rails (width 17.5mm), saving panel space, and includes a visual trip indicator (red flag) for quick diagnosis. Constructed with flame-retardant polycarbonate (UL94 V-0), it withstands temperatures from -25℃ to +60℃ and meets IEC 60947-2 standards, making it ideal for motors in pumps, fans, and conveyors.

Frequently Asked Questions

How does a motor circuit breaker protect against overloads?

A motor circuit breaker combines thermal-magnetic tripping: thermal elements detect overloads (1.1-1.5x rated current) and magnetic elements trigger instant shutdown for short circuits (10x rated current). This dual protection ensures comprehensive motor safety in electrical systems.
The motor circuit breaker features a quick-reset mechanism, allowing manual reset within 5 seconds after clearing the fault. This reduces downtime compared to fuses or traditional circuit breakers, improving operational efficiency in motor-driven equipment.
Yes, the motor circuit breaker automatically trips when any phase is lost in a three-phase system, preventing motor burnout from single-phasing. This critical feature protects motors in industrial applications like pumps, compressors, and conveyor systems.
The motor circuit breaker offers flexible mounting options, including DIN rail or surface mounting, suitable for integrated installation in motor starters and control cabinets. This versatility simplifies integration into new or existing motor control systems.
Yes, the motor circuit breaker is UL/CE certified, meeting international safety standards for use in global markets. This ensures compliance with local electrical codes and facilitates market access in Europe, North America, and other regions.

Customer Reviews

Zhang Tianming
Quick Fault Recovery for Production Lines

"In our automotive parts factory, motor overloads used to shut down production for hours while we replaced fuses. These circuit breakers reset in seconds after a fault, getting our assembly line back up quickly. The phase loss protection saved our main conveyor motor from burnout during a recent power outage, and the compact size fit into our existing motor starters without rewiring. A vital upgrade for minimizing downtime."

David Wilson
Reliable Motor Circuit Breaker for Effective Protection

The motor circuit breaker has been crucial in safeguarding our motor circuits. It promptly trips during overloads or short circuits, preventing damage to motors and other equipment. Its robust construction and easy maintenance make it a reliable choice for industrial applications. We feel much more secure with this breaker in place.
