Product details

The Siemens 3RQ4070-2SB30 is a SIRIUS 3RQ4 coupling relay in the narrow 6.2 mm housing. It takes a 24 V DC input through an optocoupler and switches a single normally-open (NO) contact rated for 6 A thermal current.

At 6.2 mm wide, this relay is designed for high-density DIN-rail mounting in control cabinets. The narrow profile means you can pack more isolation channels per meter of rail compared to a standard 14 mm interface relay. The push-in terminals keep the wiring plane clean — no screwdriver access needed above or below the terminal, which helps when rows are stacked tight.

Compliance and substance restrictions

RoHS compliant since 26 September 2024. No UL or IEC certification listing appears in the spec record; verify with the full datasheet if your site requires a specific agency mark.
