If your panel keeps tripping on motor inrush or a fault downstream, you’re losing uptime and chasing nuisance trips that waste hours—this breaker handles that by giving you a 125A thermal-magnetic trip that’s adjustable on the L type for tighter coordination, so you’re not replacing fuses every Tuesday.
We’ve been shippng the ARM3-125 to EU and UK distributors for about three years now, and what it does is meet IEC60947-2 without needing extra paperwork—CE marking’s already on the COA, and we usually have the 3P 100kA version in stock, but the 690V breaking capacity drops to 20kA, so check your line voltge before ordering.
Rated current runs 16A to 125A in ten steps (16, 20, 25, 32, 40, 50, 63, 80, 100, 125A), and the breaking capacity at 400V is 35kA for the C type, 50kA for L, 70kA for M, and 100kA for H—the arc extinguishing medium is air, so it’s basically a sealed chamber that snuffs the arc in under 50mm, which matters for panel clearances.
Mechanicla life is 8500 operations, but electrical life is only 1500—that’s pretty standard for a fixed MCCB, so don’t use it for frequent switching under load, it’s built for backup protection, not daily disconnects.
Import docs are straightforward: our company provide a packing list, commercail invoice, and a certificate of origin for EU tariff preferences, and teh thermosetting insulation handles -5°C to +55°C without issue, though high carbon steel mechanism can corrode in coastal environments if you don’t spec the optional anti-rust coating.
Our standard MOQ is 50 pieces per model, but we can negotiate lower quantities for first-time orders or sample testing. Just reach out to our sales team.
Yes, we supply IEC60947-2 and GB/T14048.2 compliance certificates with every batch. Third-party test reports are also available on request.
Absolutely. The H-type version offers 100kA at 400V. Just specify the breaking capacity type when ordering, and we'll match it to your application.
For standard 3P models in stock, lead time is 7-10 working days. Custom configurations might take 15-20 days depending on volume.
Keep it in its original packaging in a dry, clean place within the -5°C to +55°C range. Avoid humidity and direct sunlight to preserve the thermoset insulation.
