What is the overload capability of "RL" Reactors?

At Fundamental (Motor Speed Determining) Frequency not exceeding 60 Hz and Ambient Temperature not exceeding 45°C (113°F):

1. The Load (Output) Side of the Drive permits NO continuous overload (except small incidental value) and maximum 150 % overload for maximum one (1) minute, followed by return to, and stabilization at, or below, Rated Load and Temperature.

2. Line (Input) Side of the Drive permits the following Overload Profile:

All Currents are TOTAL TRUE RMS (TRMS), expressed as % of the Rated Fundamental Current (IF).

2.1 Up to and including 320 Amperes:

ITH (Thermal) = 150 % of IF Continuous
200 % of IF 30 Minutes, followed by return to, and stabilization at, or below, Rated load and Temperature 300 % of IF 1 Minute, followed by return to, and stabilization at, or below, Rated load and Temperature


2.2 From 400 to 1,500 Amperes:

ITH (Thermal) = 125 % of IF Continuous
165 % of IF 30 Minutes, followed by return to, and stabilization at, or below, Rated load and Temperature
250 % of IF 1 Minute, followed by return to, and stabilization at, or below, Rated load and Temperature
