main features
Double break point direct acting structure is adopted in the switch contact system.
Two groups of parallel contacts are used to increase the current capacity and make full use of the electric power compensation.
At the same time, the handle operating mechanism uses spring energy storage to realize fast on-off, overcomes the influence of slow human operation speed, and greatly improves the reliability of work.
Summary
LRD-125 series disconnector is mainly used as the main switch in terminal combined electrical system. It is suitable for 50/60Hz AC power distribution and control circuit with rated voltage below 400V. It can also be used to control motors, low-power electrical appliances and lighting. It is widely used in industrial and mining enterprises, high-rise buildings, commercial and family places.
The isolation switch conforms to the GB14048.3 and IEC60947-3 standards.
purpose
Small circuit breakers are used in power grid construction, renovation, real estate construction, residential, distribution lines and equipment, small circuit breakers, leakage breakers, prepaid circuit breakers, disconnectors, IC card prepaid circuit breakers.
High segmentation ability: H type 10kA, basic 6kA, N type 4.5kA
The structure is advanced, the performance is reliable and the stability is stable.
