Product Description
Product Overview
The Smart MCCB integrates a residual current relay, contactor, and MCCB into one device. It is suitable for three-phase four-wire power supply systems with a grounded neutral point, providing protection against grounding faults, overcurrent, short circuits, phase loss, and overvoltage for circuits or electrical equipment. It can also prevent electrical fires and damage to electrical equipment caused by grounding faults, as well as provide indirect contact protection against electric shock hazards to individuals.
The product complies with the standards GB14048.2-2008 and GB/T22387-2008.
The overcurrent release is electronic, and the rated current can be adjusted according to the load conditions of the circuit. The three-stage protection curve is adjustable and can work in conjunction with lower-level circuit breakers to achieve graded protection. The electronic overcurrent trip unit offers high protection accuracy and is less affected by environmental temperature and installation position, serving as an upgraded product compared to thermal-magnetic overcurrent trip units (this product is available in both economical and standard types).
It is equipped with an RS485 serial interface, allowing the setting of protection characteristic parameters through a programmer, while also meeting the requirements for communication networking.
