Electronic motor relay EPS-D 20-100A EPS-D-100A

Advanced three-phase motor protection

The EPS-D 20-100A electronic motor relay is a microprocessor-based device designed for comprehensive protection of three-phase motors of various power ratings. The use of advanced algorithms allows for precise analysis of the motor's operating status and a quick response in the event of irregularities, minimizing the risk of damage and downtime. This relay finds wide application in demanding applications such as pumps, boosters, lifts, conveyors, fans, compressors and many others.

Functionality and protection

EPS-D offers versatile protection functions, including protection against overload, ground fault and phase imbalance. Additionally, it has analog inputs for connecting temperature sensors and a current detection module, allowing for even more accurate monitoring of the motor's condition. The built-in ground fault detection module increases the safety of installation use. The relay is mounted on a 35mm rail and connected using a through connection. The rated operating current is in the range of 20-100A at a rated voltage of 160-242V AC (50/60 Hz). The IP40 protection class provides resistance to dust.
