Overview
The Bulletin 592 Overload Relay is a manual reset, eutectic alloy, thermal type overload device that protects the motor, motor controller, and power wiring against overheating due to excessive overcurrents when coordinated with proper short circuit protection. The 592-JOV16 is used for size 00 series B and D 500 line starters or for separate panel mount applications.
Key Features
- Optical indicator that becomes visible when the relay has tripped
- Manual contact test module provided as standard
- One N.O. or N.C. auxiliary contact may be field added, which physically replaces the contact test module
- Eutectic alloy thermal sensing element for reliable current detection
- Compact industrial design suitable for original equipment and retrofit applications

Compatibility & Replacements
The 592-JOV16 is compatible with Rockwell Automation Bulletin 592 family components and heater element selection. These overload relays require heater elements; refer to publication 592-TD010 for heater element selection information. For applications requiring different current ratings or configurations, consider the 592-KOV16 (32 A) or 592-BOV16 (40 A) alternatives within the Bulletin 592 series. Always verify heater element compatibility and motor specifications before installation.
