Product details

The Siemens 3RQ4118-1AE00 is an output coupler with a plug-in relay from the SIRIUS 3RQ4 family of narrow-design coupling relays. It switches one load circuit via a single change-over contact, rated for a thermal current of 6 A. The coil is rated for 115 V AC/DC, making it a direct-fit interface between a 115 V control signal and a downstream load.

The housing is only 6.2 mm wide, which saves DIN-rail space in a control panel when you need multiple isolated signal paths. The plug-in relay means you can swap the relay capsule without pulling the base wiring — useful during commissioning or fault isolation.

RoHS compliant since 26 September 2024. Export control is straightforward — AL: N, ECCN: EAR99. The packaging dimensions are 95 x 93 x 65 mm, quantity unit is one piece.
