Industrial MCCB 3P/4P 250A Thermal Magnetic Circuit Breaker 400V

Description:

This​‍​‌‍​‍‌​‍​‌‍​‍‌ circuit breaker has a rated insulation voltage of up to 800V and is made for AC 50Hz power distribution networks with a rated operating voltage of up to 400V and a rated current of up to 800A. This is the most suitable device for distributing the electrical energy the user needs while at the same time protecting the lines and the devices that are connected to the network from overloads, short circuits, and undervoltage. Also, the device can perform heavy start operations on the motor scarcely and still be able to provide the protection against overload, short circuit, and undervoltage faults reliably. This breaker is small but has a high breaking capacity and short arcing; thus, it is efficient and can be mounted in either the vertical or horizontal position. The product complies with IEC60947-2, GB14048.2, and other pertinent norms.

Overview:

The Molded Case Circuit Breaker (MCCB) is one of the central protective elements in an electrical distribution system. Its primary purpose is the protection of electrical circuits and the equipment that is connected to the same circuits against the events of overload and short-circuit. The MCCB is fitted with adjustable trip parameters and a high breaking capacity, thus, it can be a very reliable circuit protection device and at the same time allow for the selective coordination in complex electrical ​‍​‌‍​‍‌​‍​‌‍​‍‌networks.

Key application scenarios include:

- Main power distribution panels

- Motor control centers and starter panels

- Generator protection systems

- Industrial machinery power supplies

- Commercial building electrical systems

- Renewable energy installations

Engineering​‍​‌‍​‍‌​‍​‌‍​‍‌ Excellence

• Accuracy of the calibrations of the thermal-magnetic trip units enables overload and short-circuit protection to be carried out in a very safe and reliable manner
• The 50kA breaking capacity is achieved by a very advanced arc-extinguishing chamber
• The excellent heat resistance and mechanical strength of the durable thermoset housing are proven through the conducted tests

Performance Reliability

• At least 30,000 times the device can be electrically operated
• The device can be used in a very wide temperature range from -25°C to +70°C
• Besides being dual-certified to IEC 60947-2 and UL 489, the product is also fully compliant with these standards

Installation Advantages

• The breaker is 15% more compact than the standard industry breakers
• Maintenance operations are simplified due to the front-accessible accessories
• Not only the contact position but also the trip status can be easily checked through the clear indicators

Cost Efficiency

• The overall time between renewals of the component is increased by 25%, compared to normal breakers
• It is made possible for maintenance to be ​‍​‌‍​‍‌​‍​‌‍​‍‌carried
