The 6355-0048-03 is a Part Number for Encitech's OZ-4M High Voltage Protection Relay. This relay provides protection for four-quadrant operation (forward, reverse, regenerative, and static) of asynchronous motors. It includes a solid-state digital motor protection feature, which allows the relay to protect against fault currents, temperature increases, overloads, and voltage abnormalities. The relay also has an emergency stop input for manual operational shutdown and an LED indicator to show the current operational mode. Additionally, it features a single-point wiring harness for easy installation.
