Customizable 100A 3P Molded Case Circuit Breaker MCCB with ISO9001 CE CCC Certifications

Right now we’ve got stock on the 100A ZYMM1-125 three-pole version—typically ships within a week or so, and it’s packed in sturdy cardboard with internal foam, no cold chain needed since it’s just a dry electrical compnent, so lead time is usually 7-10 days for standard orders.

It handles up to 690V AC and delivers breaking capacity options of 35, 50, or 85KA, which basically means you can match it to your fault level without over-specing, and rated impulse withstand voltge sits at 8000V.

Most buyers we see are using this in industrial panels or marine switchboards where space is tight—the DMC insulating matrial keeps it compact and flame retardant if you choose that option, though you can skip the flame retardant for lower cost on less critical runs.

The metal bits inside can be steel, brass, or copper depending on what you’re after—copper gives better conductivity but adds weight, which isn’t ideal for every mounting setup, and the electrical life is rated at 3000 operations with mechanical life at 7000, so it’s not high-cycle breaker for frequent switching.

For ordering, MOQ is just one piece, so you can test a unit before committing to a larger batch—warranty runs two years, and we include standard COA with HPLC data on the injection-molded parts, though I’d double-check the colour options (white, bright grey, dark grey, or black) if appearance matters for your enclosure.

One thing that catches new users is the manual operation—there’s no motor drive built in, so it’s fixed installation with manual toggle only, and the arc-extinguishing is air-based, which works fine for most AC distribution but isn’t suited for DC circuits without derating.
