Product details

Panel fit and mounting constraints

The 3RH2131-2VB40 measures 45 mm wide by 70 mm tall by 73 mm deep — a size S00 footprint that fits standard 35 mm DIN rail enclosures without crowding adjacent devices. Snap-on mounting to the DIN rail is the primary method, with screw fixing also supported.

Coil drive and contact ratings

The 24 VDC coil draws 1.6 W closing power and includes an integrated diode surge suppressor — no external flyback diode needed when the PLC output drives it.

Lifecycle and compliance status

RoHS compliance date is 10/01/2009.

Frequently asked questions

What compliance documentation does Siemens provide for 3RH2131-2VB40?

RoHS compliance is confirmed with a substance prohibition date of 10/01/2009.

What are the clearance distances needed around this relay?

The side clearance is driven by the 10–15 ms DC arcing time.
