They are used to isolate circuits and lines that are not frequently connected and disconnected, and are widely applied in power distribution systems and automation systems in industries such as construction, electric power, petrochemical, etc. https://www.kaichuanpower.com/uploads/39389/video/202602111311342fba9.mp4 2025-07-30T16:25:54+08:00 yes no https://www.kaichuanpower.com/electrical-switch/disconnector/isolating-switch-4p.html https://www.kaichuanpower.com/uploads/39389/small/isolating-switch-4p41edd.jpg Isolating Switch 4P The core purpose of an isolating switch is to form an obvious disconnection point in the circuit, reliably isolating the equipment to be maintained from the live parts, ensuring the safety of workers and equipment. During normal operation of the circuit, it can connect or disconnect the no-load circuit as needed; during equipment maintenance, the disconnection of the isolating switch completely isolates the maintenance equipment from the power supply, preventing accidents caused by unexpected power supply. In addition, isolating switches can also be used for switching operations to change the operation mode of the power system, realizing reasonable distribution and scheduling of electricity. https://www.kaichuanpower.com/uploads/39389/video/202602111158351ddbd.mp4 2025-07-30T16:28:13+08:00 yes no https://www.kaichuanpower.com/breaker/leakage-miniature-circuit-breake/molded-case-residual-current-circuit-breaker.html https://www.kaichuanpower.com/uploads/39389/small/molded-case-residual-current-circuit-breaker6550c.jpg Molded Case Residual Current Circuit Breaker 3P 3P Molded Case Residual Current Circuit Breaker is a key electrical device integrating overload protection, short - circuit breaking and residual current protection functions. It is widely used in residential, industrial and commercial power distribution systems. Its core principle is based on the real - time monitoring of leakage current by a zero - sequence current transformer. When the residual current exceeds the set threshold (such as 30mA), the circuit is quickly cut off within 0.1 seconds, effectively preventing electric shock accidents and electrical fires. https://www.kaichuanpower.com/uploads/39389/video/202602111156244ebf9.mp4 2025-07-30T16:31:41+08:00 yes no https://www.kaichuanpower.com/breaker/leakage-miniature-circuit-breake/molded-case-residual-current-circuit-breakers.html https://www.kaichuanpower.com/uploads/39389/small/molded-case-residual-current-circuit-breakers54125.jpg Molded Case Residual Current Circuit Breaker 4P In modern power systems, ensuring personal safety and stable operation of equipment is of paramount importance. As an electrical device integrating multiple powerful protection functions, the Molded Case Residual Current Circuit Breaker 4P plays an indispensable role in residential, industrial, and commercial power distribution fields. With advanced technology and reliable performance, it provides comprehensive and efficient power protection solutions for various electricity usage scenarios. https://www.kaichuanpower.com/uploads/39389/video/2026021111543418f35.mp4 2025-07-30T16:34:20+08:00 yes no https://www.kaichuanpower.com/frequency-converter/special-frequency-converter/high-protection-variable-frequency-drive.html https://www.kaichuanpower.com/uploads/39389/small/high-protection-variable-frequency-drive27e2f.jpg High Protection Variable Frequency Drive High Protection Variable Frequency Drive (VFD) adopts high-performance vector control technology and torque control technology, featuring excellent control performance, reaching IP65 protection level.
