Compatibility & Replacements
The 592-JOV16 is a direct replacement for legacy Allen-Bradley Bulletin 592 eutectic overload relays in equivalent configurations. Verify control circuit voltage (120–600 VAC) and current rating (24 A) against your application requirements. For heater element selection and application-specific configuration guidance, consult Rockwell Automation technical documentation or contact your authorized distributor.
