Torque Limiter
The torque limiter is designed as the primary safety system to reduce the possibility of damaging the circuit
breaker racking mechanism with the RRS-3. The torque limiter attaches to the drive coupling and mates with
the racking tool. The torque limiter is set from the factory for your particular breaker, so only adjust as
needed for your specific situation.
Note: A ½ inch drive torque wrench will be required to perform this adjust-
ment.
1.
First, remove the racking tool adapter from the RRS-3 by pushing in the locking pin at the base of the
adapter, as shown. The racking adapter can then be fitted to a standard ½ inch drive torque wrench.
2.
On the de-energized and OPEN test breaker, extract the breaker’s racking handle, and fit the racking
adapter to the handle as shown in the Installation section of this manual.
3.
To determine the proper torque required to rack the breaker, first rack the breaker out, measuring
the maximum amount of torque needed. Record this value.
