They were having trouble with older oil-based breakers failing at the distribution board in the substation, especially during peak load shifts when the current spikes would cause nuisance trips and we'd lose production for half a shift while maintenance swapped contacts.
What this unit does is it handles those fault conditions with a vacuum interrupter that snuffs the arc in under 2ms of bounce time, so basically it clears the fault before the upstream protection even blinks, and we've had zero spurious shutdowns since installing the first batch.
The rated current on this one runs from 630A up to 3150A and breaking capasity is 20KA to 40KA depending on your configuration, with a peak withstand of 50KA to 100KA—the mechanical life is listed at 10,000 operations but our experience shows it'll do 15,000 or so before the contacts need looking at. Closing speed is 0.4 to 0.8 m/s and opening hits 0.9 to 1.2 m/s, and contact stroke is 9mm give or take 1mm, which is tighter tolerance than most equivalent units we've tested.
The energy-storage mechanism means you don't need a constant control power feed to keep it ready, which was a factor for our remote site where we lose auxiliary power occasionally, and protection functions cover overcurrent, overvoltage, and breaker failure monitoring.
We ordered the insert-mount version with 150mm phase distance (210mm is avaliable but that's for wider cabinets) and 3 poles, which is standdard for 12KV systems, and we usually have stock in about 30 days or so from the supplier but confirm lead time if you're running tight on a project deadline.
It's not ideal for environments above 1000m altitude without derating the voltge, and the ambient range of -10°C to +40°C means you'll need a heater if your panel sits in a cold warehouse during winter months.
MOQ is 1 unit for stock items, but if you need a specific current rating or phase distance, lead time is typically 15-25 working days depending on order volume.
Yes, it's certified ISO9001 and CE, plus it meets GB1984-2003. We'll include copies of the certificates with the packing list or email them before shipping.
Absolutely. The 3150A and 40KA configuration is available, and you can choose either 150mm or 210mm phase distance — just specify when ordering.
Store it indoors in a dry, clean place with ambient temperature between -10°C and +40°C, and keep it in its original packaging. Shelf life is about 2 years if stored properly.
The contact stroke is fixed at 9±1mm and closing speed at 0.4-0.8m/s per standard specs, but we can adjust the energy-storage mechanism settings slightly for special requests — just discuss with our engineering team.
My experience with the supplier of this circuit breaker was quite mixed, primarily focusing on the logistics and service aspects. The shipping process was unexpectedly slow and lacked clear communication at several stages. After placing the order, the initial confirmation was prompt, but subsequent updates regarding the shipment's progress were sporadic and often required me to initiate contact. The estimated delivery window provided was missed by a significant margin, causing a delay in our project timeline. The packaging, however, was adequate and the product arrived without any visible external damage, which was a positive note. Regarding service, the customer support team was responsive when reached, but their information was sometimes inconsistent. They were polite and attempted to be helpful, yet resolving the shipping inquiry took more back-and-forth than should have been necessary. There was a lack of proactive communication to inform me of the delays. I did not have extensive interaction concerning the product's quality upon arrival, as my main issues were logistical. The service attitude was good, but the execution and follow-through on logistics promises were lacking. For future orders, more reliable and transparent shipping procedures with consistent updates would be essential. The overall experience highlighted the importance of dependable logistics and cohesive customer service in industrial supply chains.
Yikes, the shipping was incredibly fast! I was genuinely surprised by how promptly the order arrived. The packaging was secure and professional, which gave me immediate confidence. Regarding the product itself, the build quality appears robust and meets industrial standards. The materials feel durable, and the overall construction seems precise. Customer service was responsive and helpful during the ordering process, answering my preliminary questions efficiently. While I haven't installed or tested the unit yet, the initial impressions based on physical inspection and the transactional experience are overwhelmingly positive. The logistical execution was flawless, and the service team was courteous. This initial phase suggests a reliable supplier for such critical components. The attention to detail in delivery and the tangible quality of the breaker itself are commendable. It arrived exactly as described, with all necessary documentation. A very smooth and professional experience from start to finish so far.
Outstanding experience from start to finish. The delivery was remarkably prompt and handled with great care, arriving well ahead of the estimated schedule. The packaging was exceptionally secure, ensuring all components were perfectly intact upon arrival. Initial inspection reveals the build quality to be superb; the materials feel robust and the craftsmanship appears precise, exactly as specified for industrial-grade protection. Communication from the seller was consistently proactive and helpful, providing clear updates and readily available to answer preliminary questions. This level of service inspires significant confidence. While I have not yet integrated the unit into our system for operational testing, the initial impressions regarding logistics, apparent quality, and customer support are thoroughly positive and highly commendable.
Fantastic experience with the delivery speed and packaging from this supplier. The shipping was incredibly fast, arriving well ahead of the estimated date, which minimized any downtime for our operations. Everything was securely packed with no signs of damage during transit, showing great care in logistics. The quality of the item appears robust and reliable, meeting our expectations for industrial-grade components. Customer service was responsive and helpful, promptly addressing my inquiries with clear, friendly communication. Overall, a smooth and efficient process that I highly recommend for anyone in need of high-voltage solutions.
