Molded case circuit breakers (MCCB) from ABB, Schneider Electric and Siemens protect feeders, motors and distribution boards from about 10 A up to 1600 A. The range covers 3-pole and 4-pole breakers with fixed and adjustable trip units, with more than 1,800 products including accessories. Stoklink ships worldwide from Turkey and quotes project volumes on request.

What's in this range

ABB Tmax XT MCCBs – XT1 to XT7 frames with thermal-magnetic and Ekip electronic trip units.
ABB Formula A MCCBs – A1 to A3 frames for general distribution.
Schneider ComPacT NSX MCCBs – frames from 100 A to 630 A.
Schneider ComPacT NS MCCBs – breakers from 630 A to 1600 A.
Schneider GoPact MCCBs – compact breakers up to 800 A.
Schneider EasyPact CVS MCCBs – CVS100 to CVS630 frames.
Siemens SENTRON 3VA MCCBs – 3VA1 and 3VA2 breakers up to 1250 A.
Siemens SENTRON 3VM MCCBs – 3VM1 breakers up to 630 A.
MCCB Accessories, Releases & Trip Units – releases and trip units.

How to choose

Frame size and rated current, with the trip unit set to the load current.
Rated breaking capacity (Icu and Ics) at the system voltage, above the prospective short-circuit current.
Trip unit: thermal-magnetic for simple feeders, electronic (LSI or LSIG) where selectivity is needed.
Poles: 3P or 4P according to the neutral arrangement. Standard: IEC 60947-2.

FAQ

What is the difference between an MCCB and an ACB?

An MCCB is a compact molded-case breaker, typically used from tens of amperes to 1600 A. An ACB is a larger, often draw-out breaker for main incomers from 630 A upward.

What do Icu and Ics mean on an MCCB?

Icu is the ultimate breaking capacity. Ics is the service breaking capacity, the share of Icu after which the breaker stays fit for service.

Do you export MCCBs and their accessories?

Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock, so request a quote with your part numbers and quantities.
