An isolating switch, also known as an isolation switch, is a crucial component used in electrical systems to disconnect a circuit or equipment from its power source for maintenance or safety purposes.
An electrical fuse is a crucial safety component in electrical systems designed to prevent damage and maintain circuit integrity. It serves as a protective barrier that helps ensure the safety and rel
Circuit breaker is a crucial electrical component designed to protect electrical circuits and appliances from damage caused by excess current. It functions as a safety mechanism by interrupting
High voltage circuit breaker is a mechanical device. The device can generate, carry and interrupt current under normal conditions. It can also carry and interrupt current in case of short circuit or o
A fuse refers to an electrical device that, when the current exceeds a specified value, uses the heat generated by itself to fuse the melt and disconnect the circuit. A fuse is a device that uses the heat ...
The molded case circuit breaker adopts a heat release contact. When the current exceeds the rated value, the contact is heated, causing the spring force to decrease, ultimately causing the contact to move ...
This article will tell you about the working principle, function, and main structure of residual current circuit breaker (RCCB), and solve customers' concerns about residual current circuit breakers, such ...
There is a difference between MCB (miniature circuit breaker) and RCCB (residual current circuit breaker) in terms of functionality, operation, sensitivity and application. MCB is mainly used to protect ci...
In the attachment you will find some test results of our lab, where you can see that we tested the leaking current, and for all samples this was measured at 24mA which is within the regulations and is okey...
SPD surge protective device manufacturer tells you,there are four types of grounding systems for low-voltage distribution systems: IT, TT, TN-S, and TN-C-S. Therefore, SPD needs to choose different wiring ...
Where are circuit breakers usually used?Mainly suitable for circuits with AC 50Hz/60Hz, rated working voltage of 240v/415v and below, and rated current up to 60a. This circuit breaker is mainly used for ov...
SPD surge protective device working principle is that when there is an instantaneous overvoltage on the power line or signal transmission line, the surge protector will release the overvoltage to limit the...
