Product details

AC-4 switching and mechanical life

The 3RA2316-8XB34-1CK2: The contactor withstands shock loads of 10.5 g at 5 ms and 6.6 g at 10 ms in both AC and DC directions, which is relevant for installations on mobile equipment or near heavy impact machinery.

Mounting flexibility and terminal details

Dimensions: 90 mm wide, 130 mm deep, 68 mm high — the S00 footprint is the smallest SIRIUS contactor frame, saving DIN rail space in dense panels.

Sourcing and lifecycle — current production

RoHS compliance date is listed as 07/01/2006 (the EU RoHS effective date), confirming the assembly meets the substance restrictions for sale in the European market.

Frequently asked questions

What is the 3RA2316-8XB34-1CK2 used for?

It is a reversing contactor assembly used to control the direction of three-phase motors — forward/reverse for conveyors, hoists, pumps, fans, and any application that needs to swap rotation without a separate reversing starter.
