Industrial Applications

1. Small Motor Protection in HVAC Systems

This circuit breaker can be used to protect small fan motors or pump motors in commercial and industrial HVAC (Heating, Ventilation, and Air Conditioning) systems, ensuring reliable operation.

Problem Solved

Prevents motor damage due to overloads from seized bearings or duct obstructions (thermal overload 5.5-8A) and safeguards against catastrophic failures from short circuits (magnetic trip 104A) in 3-phase systems up to 690V. The Class 10 trip ensures quick reaction to protect motors in typical starting conditions.

2. Conveyor Belt Drive Motor Protection

Ideal for protecting the 3-phase electric motors driving small to medium-sized conveyor belts in manufacturing or logistics facilities, maintaining operational safety.

Problem Solved

Protects the motor from sustained overcurrents caused by conveyor jams or excessive load (5.5-8A adjustable thermal release) and provides rapid shutdown during severe electrical faults like short circuits (104A magnetic release), ensuring operational safety and extending motor life in an industrial environment up to 60°C.

3. Industrial Pump Motor Protection for Water Treatment

Suitable for protecting 3-phase pump motors in water treatment plants or chemical dosing systems, handling water or non-corrosive liquids, crucial for continuous process operation.

Problem Solved

Offers reliable thermal overload protection (5.5-8A) against issues like dry running or clogged pipes, and magnetic short-circuit protection (104A) against electrical faults, which are critical for maintaining continuous operation and preventing costly downtime in process industries. Its 690V rating and IP20 (front) protection are adequate for typical indoor control panel installations.
