Product details

What this reversing contactor assembly delivers

The Siemens 3RA2316-8XB30-2BW4 is a SIRIUS reversing contactor assembly — a pre-assembled pair of contactors mechanically and electrically interlocked to reverse a three-phase motor without external wiring. It ships with two 3RT2016-2BW42 contactors (size S00) and the reversing interlock kit 3RA2913-2AA2 already fitted. At 480 V it delivers 7.6 A; at 600 V, 9 A. Horsepower ratings span 2 hp at 200/208 V to 7.5 hp at 575/600 V.

Mounting and terminal details

Both the main current circuit and the auxiliary/control circuit use spring-loaded terminals. AWG equivalents for main contacts are 1x (20... 12). The assembly occupies a 90 mm width footprint on the rail, with a depth of 83 mm and height of 84 mm. Clearance requirements: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards against the mounting surface.

Lifecycle and compliance

RoHS compliance date is 10/01/2009, indicating the assembly meets the EU RoHS substance restrictions. Vibration resistance is rated at 10.5 g / 5 ms and 6.6 g / 10 ms for both AC and DC excitation.

Frequently asked questions

What contactors are supplied inside the 3RA2316-8XB30-2BW4 assembly?

The assembly includes two 3RT2016-2BW42 contactors (size S00) plus the reversing interlock kit 3RA2913-2AA2, pre-mounted and wired for reversing duty.

What terminal type does the 3RA2316-8XB30-2BW4 use?

Spring-loaded terminals on both the main current circuit and the auxiliary/control circuit. No screw tightening needed — strip and push in.
