The Allen Bradley 193-EEEB overload relay is engineered to provide reliable protection to motors. This device allows current adjustments from 5.4 A to 27 A, accommodating a wide variety of applications. Mountable to contactors within the range of 100-C09 to 100-C23, it fits into standard setups seamlessly.
With selectable trip classes of 10, 15, 20, and 30, users can tailor the settings to align with their operational requirements. An important feature of the 193-EEEB is its ability to detect phase loss, ensuring sensitive protection against potential motor damage. The relay can reset automatically or manually, providing flexibility based on user preferences.
Auxiliary contacts include one normally closed (N.C.) contact designated for tripping and one normally open (N.O.) contact for alarms, allowing integration into more complex control systems. The relay features a screw-type control terminal for secure connections and employs a wide adjustment ratio of 5:1, ensuring precise settings.
The power dissipation is low, contributing to cooler operation, which helps maintain an efficient panel environment. This overload relay meets several certification standards including IEC 60947-4-1, UL 508, and CSA C22.2 No.14, ensuring compliance with industry requirements. The approximate motor power rating for AC-3 operations at 415 V is between 2.2 kW and 15 kW, making it a versatile solution for various motor control applications.
