Frame Circuit Breaker
Frame circuit breaker, also known as frame type circuit breaker, is an important electrical equipment used for circuit protection. A frame circuit breaker is an electrical device that can quickly cut off the circuit when detecting faults such as overcurrent, overload, and short circuit. Its main function is to protect electrical equipment and circuits from damage, effectively preventing fires and other safety issues caused by faults.
Multiple Protection Functions
The frame circuit breaker distribution cabinet has multiple protection functions such as overload, short circuit, undervoltage, and ground fault, which can achieve selective protection, avoid unnecessary power outages, and improve power supply reliability.
Flexible Installation and Connection
Supports fixed and drawer installation, can adapt to different space and usage requirements. At the same time, multiple connection methods such as horizontal and vertical wiring are provided, making it convenient for users to choose according to actual needs.
Intelligent and Communication Functions
Some framework circuit breaker distribution cabinets are equipped with intelligent release devices, which have measurement and display functions for parameters such as current and voltage, and can also achieve remote monitoring and communication, making it easy for users to grasp the real-time operation status of the equipment.
