Molded case circuit breakers, or MCCBs, are electrical protection devices used to protect the electrical circuit from excessive current, which can cause overloads or short circuits. Molded case circuit breakers can be used for a wide range of voltages and frequencies with adjustable trip settings. The MCCB uses a temperature sensitive device (the thermal element) with a current sensitive electromagnetic device (the magnetic element) to provide the trip mechanism for protection and isolation. In addition to tripping mechanisms, MCCBs can also be used as manual disconnection switches in case of emergency or maintenance operations.
ABB offers an expansive offering of Molded case circuit breakers for your projects from brands like SACE® Tmax®, TEY Lighting Panel Circuit Breakers, Thermal Magnetic and ProLine.
SACE® Tmax® T - A complete range of molded case circuit-breakers up to 3200 A. All the circuit-breakers, both three-pole and four-pole, are available in fixed versions.
