The Allen Bradley 193-EB1JC electronic overload relay is engineered to provide reliable protection for three-phase systems. With a control supply voltage set at 24 V DC, this relay can accommodate operational frequencies of either 50 or 60 Hz. The device comes with adjustable trip classes, allowing settings of 10, 15, 20, or 30, while its fixed trip class rating is established at 10. Users can select either manual or automatic reset options to suit their requirements.
In terms of current handling, the 193-EB1JC supports a rated current range from 14 to 45 A, making it suitable for various applications. The relay also includes screw clamp terminals, simplifying installation and ensuring reliable electrical connections. It has a short-circuit rating of 100 kA, providing robust safety in the event of excessive current. The insulation voltage is rated at 690 V, ensuring durability in demanding environments. Moreover, this device achieves dielectric strength of 2200 V AC for 1 minute, reinforcing its capability to withstand voltage spikes.
For added functionality, the relay is equipped with one normally open (N.O.) auxiliary contact and one normally closed (N.C.) contact, enabling versatile interfacing with other control systems. The adjustment range ratio of 5:1 provides further flexibility in setting the trip conditions, allowing for tailored performance to meet specific application needs.
