UEZ3D-125 DC smart miniature circuit breaker
●Scope of Application
■UEZ3D-125 smart breakers are integrated and independently developed products to achieve smart control and Internet of Things applications. They are a new type of product composed of sensors, microelectronics, computers, and communication technology on the basis of traditional circuit breakersIn addition to traditional overload and short circuit protection functions, the product also has remote control, electrical parameter measurement, overvoltage/undervoltage auto reclosing, fault analysis, fault alarm, RS485 communication, etc. They are suitable for AC 50Hz, rated operational voltage 65Vd.c.，rated operational current up to 100 A. It is widely used in various occasions such as 5G base stations, DC power distribution systems, etc.
●Product characteristics
■Mutiple functions：With multiple functions such as overload protection, short circuit protection, remote control, electrical parameter measurement, overvoltage/undervoltage auto reclosing, fault analysis, fault alarm, and RS485 communication
■Compact size：The high combination of mechanical releases, contact systems, arc extinguishing devices, DC motors, speed reduction mechanisms, sensors, and electronic components makes the product compact in structure and concise in appearance.
■Safety：Overload protection can be set and refined protection; short circuit protection adopts mechanical protection, with fast action and high breaking capacity.
■Intelligentization：Edge computing strategy, local processing protection; remote multiple type information collection and multiple scheme control to meet the needs of the Internet of Things
■High reliability：The operating mechanism uses efficient and reliable DC motors to provide stable power for opening and closing. The positioning system uses high-precision detection switches, which provide accurate positioning and strong anti-interference ability. The circuit board adopts anti-interference design to meet EMC requirements
■Easy installation：Adopt a modular design for MCB, which can be installed on a standard 35mm DIN rail; The control power supply and RS485 communication are connected with quick plug-in terminals, and there are various communication cable accessories available for selection.
