In terms of electricity use, most people pay great attention to it, so they will install a distribution box. So what is the function of the distribution box? What should I pay attention to when installing ...
Contactors are widely used in electrical systems, and the frequency of faults is relatively high during use. How to quickly and accurately diagnose and remove faults is the key to the normal operation
If the air switch makes a noise and does not trip, it should be replaced in time. The reason is that the noise is caused by poor contact inside and there is a potential safety hazard if it is used aga
Contactor is an electromagnetic automatic switch. It is an automatic electrical appliance that relies on electromagnetic force to close or separate contacts. It is used to connect or disconnect the mo
The early circuit breaker of China in the world was produced in 1885. It is a combination of knife head and over-current release.In 1905, the air circuit breaker with free tripping device was born. Si
The circuit breaker is a very basic low-voltage apparatus. The circuit breaker has overload, short circuit and undervoltage protection functions, and has the ability to protect lines and power supplie
Current Rating: 100A; Metallic Compact Consumer Unit·|P3X Safety; Multiple cable entry knockouts; Rigid, raised and Offset DIN rail design; Earth and neutral blocks fixed as standard; lnsulated comb busbar...
Product introductionJVL29-63 is applicable to residual operating current with rated voltage 230V/400V,frequency 50/60HZ and rated current up to 63A. It is used to perform the human electricity shock p
The principle of the AC contactor is that the power is pulled in, the main contact is closed and turned on, and the motor runs. This article introduces the self-locking circuit of the AC contactor and
What is the difference between an Electronic Tripper and a Thermomagnetic Tripper 1. Thermal magnetic trip
Tripper is an accessory for remotely operated tripping. When the power supply voltage is equal to any voltage between 70%-110% of the rated control power supply voltage, the circuit breaker can be reliably...
Leakage circuit breaker is mainly composed of zero sequence current transformer, electronic component board, leakage release and circuit breaker with overload and short-circuit protection. The leakage
