Panel fit and mounting flexibility
The 3RA2316-8XB37-1CM2 is a SIRIUS reversing contactor assembly — two contactors mechanically interlocked in a single housing, so a motor can be reversed without external interposing relays or contactor stacks. The size S00 frame keeps the footprint compact: 90 mm wide, 68 mm tall, 130 mm deep. Clearance around the unit is specified at 6 mm upwards, downwards, and sideways, with 0 mm backwards — meaning it can sit flush against the back panel without derating.
Rated output and contact configuration
At 480 V 60 Hz the current rating is 7.6 A; at 600 V it's 9 A. Horsepower ratings run from 2 hp at 200/208 V up to 7.5 hp at 575/600 V — so this covers common North American motor sizes in a single unit. Each direction of rotation has 3 normally-open main contacts (6 instantaneous contacts total), which is the standard count for a three-phase reversing starter.
Lifecycle and sourcing posture
Mechanical life is rated at 10,000,000 operating cycles typical for the contactor, which is standard for the S00 frame in light-duty reversing applications.
