1658-G21-02-P10-25A is a type of circuit breaker, and its application field and working principle are explained in detail below.

Application Field

The 1658-G21-02-P10-25A is mainly used for commercial, residential, and industrial applications. It is suitable for low and medium voltage systems such as HV/LV/MV tripped, auto reclosing, fault detection, supervision and other control functions, including AC 50/60Hz, DC and pulsed power, stability and reliability. Due to its diverse application, it is often applied to power grids, electric railways, buildings, hospitals, municipalities, and many other areas.

Working Principle

The 1658-G21-02-P10-25A is manufactured with a high performance contact mechanism and reliable arc extinguishing components which guarantee the safety and long service life of the device. The contacts of the device are divided into main, auxiliary and load terminals which are all of high quality, electric grade silver-tungsten alloys. The device also includes a stainless steel frame, insulated surface area, an operational handle with open and close positions, and an electric arc extinguishing system with a mechanical braking link.

The working principle of the device is that the electric current is detected on the tripswitch by an infra-red or micro-optic sensors. When the trip switch receives the current, it will send a signal to the contact components, leading the contacts to disconnect the circuit and the handle to achieve the open position. When the circuit breaker is turned off, the power supply is cut off, and the machine will restart the electric current after the handle is reset to the original position.

Moreover, the device is designed to break the current during a power failure, meaning that the main and auxiliary contacts will separate, and the power coming out of the outlet will no longer be supplied. This is also a protective feature that prevents damage to electric motors and heaters.

1658-G21-02-P10-25A has a self-protection capability, meaning that it is temperature-resistant and is self-contained, which allows for unrestricted use. This feature protects it from high current levels and prevents the circuit from being burned out or damaged.

Conclusion

1658-G21-02-P10-25A is a type of circuit breaker that is suitable for a wide range of applications, from residential to industrial, as well as for low and medium voltage systems. It is manufactured with reliable contact components and a high performance contact mechanism, as well as an electrical arc extinguishing system that offers durability and safety. Furthermore, the device is designed with a self-protection capability that prevents it from being damaged by high current levels.
