Industrial Applications

1. Overload and Short-Circuit Protection for Industrial Water Pumps

This circuit breaker is ideal for protecting small to medium-sized industrial water pumps (e.g., up to 7.5 kW) that operate on a three-phase AC supply up to 690V. Its adjustable thermal release (7-10A) precisely matches the pump motor's full load current, preventing damage from sustained overloads, while the 130A short-circuit release provides immediate disconnection during fault conditions.

Problem Solved

Prevents motor burnout and system damage in industrial pumping stations due to overcurrents and short circuits, ensuring continuous and safe water circulation.

2. Integrated Motor Starter and Protection for Conveyor Belts

The 3RV2011-1JA15 can serve as a compact motor starter and protective device for conveyor belt systems in manufacturing or logistics. The 7-10A adjustable range covers common conveyor motor ratings, and the integrated thermal and magnetic protection ensures reliable operation and safety, preventing motor damage from jams or mechanical overloads. The DIN rail mounting simplifies installation within control panels.

Problem Solved

Offers efficient starting and robust protection for conveyor motors, safeguarding against operational disruptions and equipment failure caused by electrical faults or mechanical stress.

3. Overcurrent Protection for Commercial HVAC Fan Motors

This circuit breaker is well-suited for protecting the fan motors in commercial HVAC (Heating, Ventilation, and Air Conditioning) systems. With its capacity to handle motors up to 7.5 kW and operation at up to 690V AC, it effectively protects against both thermal overloads from continuous operation or restricted airflow and immediate short circuits, ensuring system longevity and safety. The IP20 rating is suitable for enclosed control panels.

Problem Solved

Secures critical HVAC fan motors from electrical overloads and short circuits, preventing costly downtime and ensuring consistent climate control and air quality in commercial and industrial facilities.
