Operating Mechanism for MCB(DPN) Miniature Circuit Breaker (3052112)

The operating mechanism is a mechanical system that drives the contact opening and closing movements. Its core functions are: ① providing sufficient power to quickly close or open the contacts; ② maintaining stable contact pressure in the closed state; ③ quickly triggering opening in the event of a fault (in conjunction with the release).

Operating Mechanism

Operating Mechanism Manufacturer | HAIPART


Within the confines of a cubic inch, HAIPART deconstructs the linear thinking of traditional transmission. Through the staggered layout of asymmetric planetary gear trains, unidirectional torque is decomposed into a three-dimensional force field. This mechanical structure, similar to the DNA double helix, enables heavy-duty robotic arms to lift thousands of pounds of steel while achieving micron-level position corrections.


Why Choose HAIPART Operating Mechanism?



✅Perfect integration of millisecond-level power-off and temperature sensing



✅Transient control of electromagnetic systems



✅Five-layer vacuum-coated bimetallic strips, with a thermal deformation response speed 1.8 times faster than the national standard



Applications:

Suitable for heavy industry, new energy, smart factories, and other applications.


FAQ

Q1:What is the core function of the operating mechanism?

A1:It enables circuit breaker opening and closing operations and is equipped with mechanical interlocking function to ensure that the circuit breaker cannot be closed under abnormal conditions such as lack of energy storage.


Q2:What are the differences between the operating mechanism and the trip unit?

A2:Operating Mechanism: Only controls the opening and closing actions of the circuit breaker; no protection function.

Trip Unit: Possesses overload and short-circuit protection functions, triggered by mechanical or electronic signals.


Q3:How to choose the operating mechanism type?

A3:The manual operation mechanism is suitable for scenarios requiring frequent operation; the electric operation mechanism supports remote control.


Q4:How should the rated current be matched to the operating mechanism?

A4:The mechanism must support the maximum breaking current of the circuit breaker, and the motor circuit must be equipped with a mechanism with a long mechanical life.


Q5:What are the requirements for the installation location of the operating mechanism?

A5:Electric mechanisms should be located close to the control box to minimize cable length; manual mechanisms should be installed in an easily accessible location.


Q6:How can we verify the reliability of the operating mechanism?

A6:Manual operation: Perform 10 consecutive opening and closing cycles to check for mechanism jamming or abnormal noise.

Electric operation: Simulate remote signals to verify the action time.


Q7:What are the common causes of jamming in the operating mechanism?

A7:Corrosion or deformation of transmission components, aging of springs, burnt-out coils of electric mechanisms, or open circuits in the control circuit.


Q8:What are the prices of your products?

A8:Product prices vary depending on the model, specifications, and quantity. Please consult the sales team or check the official website for details.


Q9:What after-sales services do you provide?

A9:We provide comprehensive after-sales services, including product consultation, technical guidance, installation and commissioning, repair and replacement, and warranty.


Q10:How can I contact your technical support?

A10:Technical support can be contacted through the official website, customer service hotline, or email.
