Product details

The Siemens 3RK1911-2BR10 is a connector socket insert — Han Q4/2 straight, 4 contact sockets rated for 4 mm² conductors, designed for the starter side of subsegment and spur line drops in a SIRIUS motor feeder architecture.

This insert mates with the Han Q4/2 hood/housing on the motor starter side, carrying the spur or subsegment power feed. The 4 mm² contact rating handles the typical branch circuit conductor size for SIRIUS S00 contactor assemblies. Straight orientation keeps the cable exit aligned with the DIN-rail wiring channel.

Frequently asked questions

What is the substance prohibitance date for the 3RK1911-2BR10?

The substance prohibitance date is 01.05.2012, confirming RoHS compliance for EU-market installations.

Will the 3RK1911-2BR10 drop into a panel specified around the 3RT1015-1BB42 contactor?

The 3RK1911-2BR10 is a connector socket insert for the starter-side subsegment/spur line, not a direct mechanical substitute for the 3RT1015-1BB42 power contactor. It interfaces with the Han Q4/2 connector system used on SIRIUS S00 starters, so if the panel uses that connector family, the insert fits without rewiring.
