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.

G5PZ-X High-precision arc control using minimum space with our unique simulation technology
Arc controlled by permanent magnet
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.
