Arc Chamber
HAIPART
3058006
During continuous testing in an 80°C high-temperature chamber, conventional trip units exhibited a 15% performance deviation due to magnetic attenuation. Our CeramMag™ ceramic composite magnet technology maintains an operating accuracy of ±2% within a temperature range of -55°C to 125°C, making it the preferred solution for applications such as metallurgy and deep-sea equipment.
Applications:
It can be used in a variety of scenarios, including smart buildings, new energy vehicle charging stations, and specialized industries.
FAQ
Q1:What is the core function of the magnetic trip unit?
A1:Instantaneous short-circuit protection uses the principle of electromagnetic induction to detect sudden current changes and cuts off the circuit in milliseconds to prevent equipment damage.
Q2:What is the difference between a magnetic trip unit and a thermal trip unit?
A2:Thermal trip: Only responds to overload current (delayed action), no short-circuit protection.
Magnetic trip: Only responds to short-circuit current (instantaneous action), no overload protection.
Q3:What are the requirements for the installation location of the magnetic trip unit?
A3:By placing it close to the load side, the impact of line impedance on protection sensitivity is reduced.
Q4:How to verify the reliability of the magnetic trip unit's operation?
A4:The short-circuit test simulates fault current to verify that the trip unit operates within 5ms, while the overload test continuously operates at 1.2 times the rated current to ensure that the thermal trip does not malfunction.
Q5:What are the common causes of malfunctions in magnetic trip units?
A5:Electrical interference and mechanical jamming.
Q6:What are the safety standards for magnetic trip units?
A6:Electrical safety must pass the IEC 60947-2 short-circuit withstand test (e.g., 50kA/1s), and outdoor applications must meet the IP54 protection rating (dustproof and waterproof).
Q7:Special design of magnetic trip unit in low-voltage power distribution?
A7:Selective protection and shunt trip extension.
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.
