If you're specifying breakers for a Tier III data center with 2000A busbars and backup generators that can dump 100kA fault current into the system, the MT12N1 is where most buyers land. We've seen these handle the inrush from UPS banks without nuisance tripping—that Micrologic release does the heavy lifting on curve shaping. The electric operation is pretty much mandatory for remote switching in unmanned substations.
Breaking capacity hits 150kA at AC400V, which covers most building distribution scenarios even with transformer oversizing. Current range runs from 630A to 6300A, so you can use the same platform for feeder breakers and main incomers. The intelligent release supports Modbus and Ethernet natively, no gateway needed for BMS integration. Mechanical life is tens of thousands of operations—(roughly 20,000 cycles at rated load before contact wear becomes a consideration). Poles are 3P or 4P, fixed installation, IP30 enclosure.
For large commerical buildings you'll typically configure ground fault protection on the 4P version to meet code requirment for service entrance. One thing: the high-speed trip characteristic (about 2-3 cycles) makes it less suited for motor starting appliction where you need intentional delay for inrush—use a thermal-magnetic MCCB for that. It's actually better than most frame breakers for selective coordination because the Micrologic lets you dial -time delay bands precisely.
We usually stock the MT12N1 in 1600A and 3200A variants with silver-copper alloy terminals standardized for horizontal or vertical bus connections. Ordering lead time is about 20 days or so for custom ratings outside those two sizes. MOQ is one unit, but you get a full COA and CE declaration with each shipment.
We can start from a single unit for testing or small-scale deployment, but batch orders typically kick off at 10 units for better pricing.
Standard production takes around 15-20 working days. Custom configurations like specific communication protocols or pole arrangements may add a few extra days.
Yes, we include all three certifications — ISO9001, CE, and CCC — in the packing documentation. Just let us know if you need originals or digital copies.
Definitely. The connection terminals are standardized for both horizontal and vertical installations, so you don't need extra adapters or modifications.
Store it in a clean, dry place, ideally indoors, at temperatures between -5°C and 40°C, and keep the IP30 enclosure intact to avoid dust buildup.
