Molded case circuit breakers (MCCBs) provide essential MCCB protection. This is by safeguarding electrical circuits from various faults. Primarily, MCCBs protect against overloads. The latter occurs when the current exceeds the circuit’s capacity for an extended period. They also offer MCCB short-circuit protection.
The typical lifespan of an MCCB can vary depending on usage, environmental conditions, and maintenance. Generally, MCCBs are designed to last between 15 to 30 years. Regular maintenance and periodic testing ensure the MCCB functions correctly throughout its service life. For specific details about the longevity of particular models, such as the iALLWAY MCCBs, consult the manufacturer’s guidelines.
No, molded case circuit breakers do not protect humans from electric shock. MCCBs mainly protect electrical circuits from damage. They even prevent fires caused by electrical faults. For protection against electric shock, residual current devices (RCDs) or ground fault circuit interrupters (GFCIs) are typically used in conjunction with MCCBs.
Several reasons are attributed to the failure of an MCCB:
Yes, many MCCBs come with MCCB earth fault protection. This feature detects ground faults that occur when electricity flows to the earth due to insulation failure or other issues. The MCCB will trip to disconnect the circuit. Thus, it reduces the risk of electric shock and potential damage.
The range of MCCB protection typically includes protection against overloads, short circuits, and earth faults. For instance, the iALLWAY iALM7 series provides comprehensive protection for various applications, including AC and DC circuits.
The iALM7DC series offers protection with a maximum rated voltage of 1500V and a breaking capacity of up to 20kA, while the iALM7HU series supports up to 50kA breaking capacity at 800V AC.
To ensure effective operation, an MCCB should meet several requirements:
