Arc Chamber

Low-Voltage Arc Chamber Manufacturer | HAIPART


HAIPART's enhanced arc extinguishing system, developed for heavy industrial applications, achieves zero residual current interruption with its unique plate topology. Our adaptive arc extinguishing technology has been used in harsh environments such as the steel and chemical industries, providing equipment with the ultimate guarantee of "millisecond-level response and zero-error protection."


Why Choose the HAIPART Arc Chamber?



✅Interrupting Capacity: Withstands 10kA/400V short-circuit current




✅Lifespan: ≥20,000 mechanical operations




✅Safety: Red insulating support plate provides clear polarity identification



Applications:


Suitable for low-voltage electrical equipment such as AC contactors and molded case circuit breakers below 400V, especially suitable for high-voltage applications (such as photovoltaic inverters and elevator control systems).


FAQ

Q1:How to match the number of poles of the arc chamber to the circuit breaker?

A1:1P/2P arc chambers are suitable for lighting and socket circuits; 3P/4P chambers are suitable for three-phase electrical equipment, with a breaking capacity of ≥6kA.


Q2:What are the common signs of damage to the arc chamber?

A2:The circuit breaker tripped;Cracks or burn marks appeared on the outer casing of the arc-extinguishing chamber.


Q3:What is the function of the arc chamber?

A3:The main function of the arc chamber is to quickly extinguish the arc when the circuit is interrupted, preventing equipment damage and circuit failure.


Q4:How to select the arc chamber size based on breaking capacity?

A4:For 6kA (residential/small commercial), select a narrow size of ≤60mm; for 10kA (industrial), select a wide size of ≥80mm.


Q5:How to choose the type of arc chamber?

A5:Based on the arc extinguishing principle, the following can be selected: grid plate, magnetic blowout, or narrow-slot arc chamber; Based on the circuit type, AC circuits should prioritize grid plate/narrow-slot, while DC circuits must use magnetic blowout or staggered grid plate.


Q6:What are the prices of your products?

A6:Product prices vary depending on the model, specifications, and quantity. Please consult the sales team or check the official website for details.


Q7:What after-sales services do you provide?

A7:We provide comprehensive after-sales services, including product consultation, technical guidance, installation and commissioning, repair and replacement, and warranty.


Q8:How can I contact your technical support?

A8:Technical support can be contacted through the official website, customer service hotline, or email.


Q9:Do your products have quality certifications?

A9:Our products have passed international and domestic quality certifications such as ISO 9001 and CE.
