Allen-Bradley 193-EC2ZZ Electronic Motor Protection Relay

Allen-Bradley 193-EC2ZZ E3 Plus Electronic Motor Protection Relay provides dedicated motor protection by monitoring motor current with an external current transformer and delivering a controlled trip to the contactor in overload conditions, supporting motor loads up to 5,000 A full-load current across the 9-5000 A range. Suffix ZZ denotes an internal ground-fault sensing option, enabling ground-fault protection configured for a 1–5 A sensing range as part of the Series B & C EC2ZZ family. Designed for direct-contactor mounting and panel installations, the 193-EC2ZZ integrates with standard Allen-Bradley motor-control assemblies, offering compact protection within the E3 Plus family. Used with 3-phase motors in industrial settings, the 193-EC2ZZ works with standard Allen-Bradley contactors and control wiring to deliver reliable protection, reducing motor damage from overloads and helping maintain line uptime in panels or control enclosures.
