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.
