Eutectic Alloy Type

Bulletin 592

A Rockwell Automation exclusive — overload relay is the same for all three trip classes (10, 20, and 30) for each Starter Size.
Trip current ratings are easily selected by choosing the proper heater element — no need to change the overload relay.
The trip-free mechanism means you still have overload protection even if the reset button is held down.

Bulletin 592 overload relay is a manual reset, eutectic alloy, thermal type overload device. When coordinated with the proper short circuit protection, the overload relay is intended to protect the motor, motor controller, and power wiring against overheating due to excessive overcurrents.
All Bulletin 592 block type relays are furnished with an OPTICAL INDICATOR which becomes visible when the relay has tripped. A manual contact test module is provided as standard on block type Bulletin 592 overload relays. One N.O. or N.C. auxiliary contact may be field added to block type Bulletin 592 overload relays. This extra contact module physically replaces the contact test module.
