MCCBs | Moulded Case Circuit Breakers

What are MCCBs?

MCCBs are commonly referred to as Moulded Case Circuit Breakers and are operated electronically by using a switch to keep a secure electrical circuit from being damaged, typically caused by overvoltage and current. The consequences would be a short circuit or overheating.

Enrgtech offers a wide selection of high-caliber products from renowned manufacturers, including Siemens, Schneider Electric, ABB, and Eaton. With the help of our products, you can meet the needs of all your electrical systems and needs for energy distribution with trustworthy circuit protection. A wide range of molded case circuit breakers is available, each with a different current rating, voltage rating, and breaking capacity.

MCB vs MCCB

MCBs and Moulded Case Circuit Breakers are both circuit breakers, although key differences still exist that characterize them as compatible with a relative task. The fundamental distinction between the two is the capacity; MCBs have an interrupting rating of fewer than 18,000 amps and a rating of under 100 amps. As a result, the trip characteristics might not be changed because they are designed for low circuits.

At the same time, an MCCB is made available with compatibility trip features for loads that practice higher potential applications. Depending on the application, an MCCB might offer amps as high as 2500 or as low as 10. The range of Moulded Case Circuit Breakers' interrupting ratings is from 10,000 amps to 200,000 amps.
