We're looking at a 6000A breaking capacity unit that trips fast on earth leakage — electromagnetic release, no thermal delay built in. What it does basically is cut power the moment current starts sneaking out through a ground path or a person, so it's more about preventing electrocution than protecting wires form overloads (though it pairs with MCBs for that). Most buyers go with the 30mA sensitivity for general residential circuits, but you've got options from 10mA up to 500mA depending on how sensitive you need the detection.

And it can be a bit confusing if you haven't ordered these before — the ID series comes in 2-pole for 230VAC or 4-pole for 400VAC three-phase work, with rated currents from 16A all the way up to 100A. The Type AC handles sinusoidal AC leakage, while Type A catches both AC and pulsating DC leakage; pick Type A if you've got electronics like variable speed drives or rectifiers in the circuit, otherwise Type AC is cheaper and usually fine. You'll want to match the sensitivity to the appliction — 10mA for wet environments or medical areas is typical, 300mA or 500mA is more for fire protection on main feeders.

These RCCBs are strictly for fixed installation with pin-type terminals, so they're designed to snap onto DIN rails inside distribution boards, not for portable use or open wiring. We usually have stock on common combinations — 63A 30mA Type AC 2P is the fast mover — but the 100A or Type A variants might need a lead time check (usually 2-4 weeks). Also, they're certified to IEC/EN 61008 with CE, ISO9001, and CCC, which means they'll pass inspection in most commercial or residential projects.
The HS code is 8536200000 if you're dealing with customs — that's for automatic circuit breakers for voltage under 1000V, which covers this one. One thing you might not think to ask: the terminal torque specs. These pin-type connections need to be tightened to about 2.5 Nm per screw (give or take 0.3 Nm), and if you overtighten you risk cracking the housing or stripping the threads — which isn't immediately obvious until the unit fails in service. Not suited for high-ambient-temperature environments above 55°C either, so keep that in mind for boiler rooms or outdoor enclosures.

Anyway, ordering details: MOQ is typically 100 units for standard configurations, but we can sometimes do 50 units or so on the 30mA common sizes if you ask. The packaging is individual boxes with inserts, palletized for freight — no frills but sturdy enough for transport. Teh price per unit drops noticeably at 500+ pcs.
Minimum order quantity is 100 units per model, but we can provide up to 5 samples at cost for testing and certification purposes.
Lead time is typically 20-25 working days after order confirmation and payment. Stock items can ship within 7 days.
Yes, we include a certificate of conformity per IEC/EN 61008 with every batch, and we can share scanned copies of CE, CCC, and ISO9001 certificates upon request.
Yes, the 100A rating is available in both 2P and 4P configurations. For 230VAC single-phase, the 2P version works perfectly.
They come in standard export cartons of 50 pieces each. If you need individual blister packaging or poly bags for retail, let us know and we can adjust.
