Product details

Switching capability and coil draw

The 3RH2131-1VB40-ZX95: The DC coil draws 1.6 W closing power, and the built-in diode surge suppressor clips the inductive kickback — no external flyback diode needed on the coil drive.

Environment and compliance

Operates from -25 to +50 °C, stores from -55 to +80 °C, with relative humidity down to 10 % — covers most indoor industrial enclosures without climate control. Pollution degree 3 rating means it tolerates conductive dust and occasional condensation — typical for control panels near machinery or washdown zones.

Frequently asked questions

What is the switching current rating of 3RH2131-1VB40-ZX95?

It is designed for auxiliary circuits, not motor starting.
