New products in the G5PZ series
Compact size and bi-directional DC high voltage switching materialized
G5PZ-X is a compact, high-capacity DC power relay based on the popular G5PZ series. The 200 VDC/20 A bi-directional DC switching performance has been achieved in a size comparable to the conventional G5PZ series. DC high-voltage support allows for a wide range of applications, including ESS.

Conventional G5PZ series
G5PZ-X High-precision arc control using minimum space with our unique simulation technology
Arc controlled by permanent magnet
![By applying Fleming's left-hand rule and using permanent magnets to extend and shut off arcs](/us-en/sites/components.omron.com.us/files/2022-07/onboard_253_2_03_en.png)
An important point in switching DC loads is to increase the contact gap to suppress arcing, but the larger the contact gap, the larger the size.
Therefore, as a way to control the arc with a minimum contact gap, permanent magnets are used to extend and shut off the arc.
Realizing DC switching performance in a size as small as that of conventional products by making full use of CAE*1 analysis technology
The arc extending direction and cutoff distance vary slightly with the size (magnetic force) and position of the permanent magnet as well as the contact gap. G5PZ-X uses proprietary CAE analysis technology to accurately simulate these changes, and is designed in an optimal arrangement that allows highly precise arc control in a minimum amount of space. As a result, the contact gap is minimized and DC switching performance of high voltage and high current is achieved in a size as small as the conventional G5PZ series.
