The 193-EB1JD electronic overload relay is part of Allen Bradley's E1 Plus relays, built to deliver reliable protection for motors in a three-phase setup. The operating current range of this relay spans from 28 to 90 A, giving it versatility in different applications. This relay is designed with a fixed trip class of 10, with options for adjustable trip classes set at 10, 15, 20, or 30 to accommodate varying motor characteristics. The screw clamp terminals enable straightforward connection to the electrical system, simplifying installation and enhancing reliability.
Designed for use within a short-circuit rating of 100 kA, the relay delivers robust protection when matched with appropriate circuit safeguards. The insulation voltage of the device is rated at 690 V, while it maintains a dielectric strength of 2200 V AC for one minute, which is essential for maintaining safety standards in operational environments. It supports a control supply voltage of 24 V DC and is compatible with frequency ratings of 50 or 60 Hz.
For additional functionality, this relay includes auxiliary contacts configured as one normally open (N.O.) and one normally closed (N.C.). The adjustment range ratio of this electronic overload relay is set at 5:1, allowing finer control over the current settings. Together, these features make the 193-EB1JD a suitable choice for maintaining motor protection and enhancing operational reliability.
