Reversing starter for motor control panels
The Siemens 3RA2210-1HA16-2BB4 is a SIRIUS reversing starter in size S00, combining a contactor, overload relay, and circuit-breaker in one assembly for forward/reverse motor control. The 24 V DC coil draws 4 W holding power, letting the control transformer and PLC output drive it without oversizing.
Trip class and protection
The supplied circuit-breaker (3RV2011-1HA10) provides magnetic short-circuit protection, while the thermal bimetallic overload handles sustained overcurrent.
Dimensions and panel fit
At 170 mm high, 90 mm wide, and 97 mm deep, the S00 frame fits compact enclosures — clearance of 50 mm above, 10 mm below, and 10 mm to the side meets the manufacturer's spacing for heat dissipation. The supplied link module (3RA1921-1DA00) and contactor (3RT2016-1BB42) are pre-assembled, reducing wiring time and error risk during panel build.
Lifecycle and sourcing
RoHS compliance date is 2009-01-10 (substance prohibition); the unit also carries CE and other standard industrial approvals by design.
