Product details

Reversing contactor assembly, size S00

The Siemens 3RA2315-8XB30-2BB4 is a SIRIUS reversing contactor assembly built from two 3RT2015-2BB42 contactors on a common mounting plate, wired for forward/reverse motor control. Size S00 keeps the footprint tight — 90 mm wide, 84 mm tall, 83 mm deep — so it wires up clean in a crowded panel without hogging DIN rail.

Duty ratings and terminal work

Current draw at 480 V is 4.8 A; at 600 V it pulls 6.1 A. The magnet coil also terminates on spring-type terminals, same wire range. Clearance around the assembly: 6 mm upward, forward, downward, and to the side; zero clearance needed backward.
