Features and applications:
489-P1-HI-A20-E This relay is suitable for applications that require the management and protection of synchronous and induction generators, especially where high accuracy, stability and durability are required.
It provides trip and alarm protection, including neutral line overvoltage and undervoltage and other protection functions.
The P1 code on the relay indicates a phase current input of 1 amp phase CT secondary side, while the E at the end indicates an enhanced display with a larger LCD screen.
It supports analog, voltage, and digital inputs that are critical to the operation of the device and have very specific characteristics.
Meet the standard:
The 489-P1-HI-A20-E relay complies with a range of international standards and specifications. These include dielectric voltage resistance, shock voltage resistance, insulation resistance, damping oscillation, electrostatic discharge, RF immunity, fast transient interference, surge immunity, conducted RF immunity, radiation and conducted emission, sinusoidal vibration, power magnetic immunity, voltage plunge and interruption, inlet protection, and environmental protection (cold and hot).
