MCCB 3P/630A Molded Case Circuit Breaker for Power Distribution

Product​‍​‌‍​‍‌​‍​‌‍​‍‌ Overview

Molded Case Circuit Breakter (MCCB) is a device for a 50Hz power distribution network of AC with a rated operating voltage of up to 400V, and a rated current of up to 800A. Along with giving the electric supply a stable flow of power, the unit keeps the wires and the rest of the equipment safe from extra current, short-circuit, and even undervoltage situations. Moreover, the device is also suitable for the starting of a motor that is not used frequently and is guaranteed to provide protection against various abnormal electric processes. With its small size, it has a high breaking capacity, and a very short arcing time, thus this MCCB would be great for both industrial and commercial uses. It is possible to implant the breaker in both ways, vertically as well as horizontally, thus it would be easier to decide where the installation should be done. The product complies with standards IEC60947-2, GB14048.2, and other related international norms.

Key Features & Functions

The MCCB is the main protective device in the power supply systems. The first and foremost features of this device are:

• Circuit Protection: Helps to protect the electric wiring and the appliances that are attached to the power supply from the dangers of overheating and short-circuiting.
• Adjustable Trip Settings: Enables the user to selectively coordinate the network by micro-adjusting the trip settings.
• High Breaking Capacity: The device is equipped with the ability to cut off very high short circuit current quickly and smoothly. So, the device ensures the safety of the entire power system.
• Compact & Flexible Design: The unit occupies little space and can be installed either vertically or horizontally.
• Reliable Motor Protection: Dangerous situations like overload and short circuit can be avoided if, the device supports the starting of the motor that is rarely used, by providing it with protection.

Applications

• Industrial power distribution
• Commercial building electrical systems
• Motor protection in factories
• Control panels and switchboards
• Electrical isolation and maintenance

Compliance & Standards

• IEC60947-2 – Switchgear and controlgear of low-voltage
• GB14048.2 – Low-voltage circuit breakers
• Other International Standards

The Molded Case Circuit Breaker (MCCB) is the right combination of a great conductor, small design, and dependable safety, which makes it an indispensable unit of power distribution systems for industries, commercial enterprises, and ​‍​‌‍​‍‌​‍​‌‍​‍‌utilities.

The​‍​‌‍​‍‌​‍​‌‍​‍‌ main application scenarios of the MCCB are:

• Primary distribution boards and power panels
• Motor control centers and starter units
• Generator protection and backup systems
• Power supply for factory equipment
• Electrical installations in commercial buildings
• Energy storage and solar-powered systems

By virtue of its versatile structure, the MCCB is capable of adjusting the protection parameters which can be individualized for different types of loads, such as a simple lighting circuit or a heavy-duty motor load. To have a reliable performance it must be able to avoid the occurrence of electrical fires, the breaking of the equipment, and the power failure, hence, the MCCB is the core element of the present electrical infrastructure in the industrial, commercial, and utility ​‍​‌‍​‍‌​‍​‌‍​‍‌sectors.
