Reversing contactor assembly in size S00
The 3RA2316-8XB34-1DG4 is a Siemens SIRIUS reversing contactor assembly — two contactors in one package for forward/reverse motor control without external interlocking. Frame size S00 keeps the footprint compact: 68 mm high, 90 mm wide, 145 mm deep. It ships with two 3RT2016-1DG44 contactors already installed, each rated for AC-3 switching up to 690 V. At 400 V the assembly handles 4 kW; at 480 V it delivers 7.6 A, and at 600 V it reaches 9 A. Horsepower ratings span 2 hp at 200/208 V up to 7.5 hp at 575/600 V.
Mounting and wiring for panel integration
Snaps onto 35 mm standard mounting rail (DIN EN 60715) and can also be screw-mounted. Clearance to adjacent components: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards. Wire termination uses screw-type terminals on both the main current circuit and the magnet coil.
Duty cycle and environmental limits
Rated for 10 million mechanical operations typical. Maximum switching rate in AC-3 or AC-3e duty is 750 operations per hour. Shock resistance: 10.5 g for 5 ms, 6.6 g for 10 ms on both AC and DC axes. Lifecycle status is current production — this reversing assembly is an active catalog line from Siemens.
