You should use selenium for this.
You will also have to install proper driver (chromedriver or gekodriver)
(I use firefox, so gekodriver)

The following code is almost correct, you can finish:

import selenium
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from bs4 import BeautifulSoup
from pathlib import Path
import os
import PrettifyPage
import time


class FetchEaton:
    def __init__(self):
        os.chdir(os.path.abspath(os.path.dirname(__file__)))
        url = 'http://www.eatonpowersource.com/cross-reference/'
        self.pp = PrettifyPage.PrettifyPage()
        self.get_xref_data(url)
    
    def get_xref_data(self, url):
        browser = self.start_browser()
        browser.get(url)
        time.sleep(1)
        searchbox = browser.find_element(By.XPATH, '//*[@id="Criteria_CompetitorPartNumber"]')
        searchbox.clear()
        searchbox.send_keys('0330D0')
        btn = browser.find_element(By.XPATH, '/html/body/div[5]/section/div/section/div[1]/div[1]/span/aside/form/div[1]/div/span/button/i').click()
        time.sleep(2)
        table = browser.find_element(By.XPATH, '/html/body/div[5]/section/div/section/div[1]/div[2]/div[3]/div/div[1]/div/div/table')
        allRows = table.find_elements(By.TAG_NAME, 'tr');
        for row in allRows:
            cells = row.find_elements(By.TAG_NAME, 'td');
            for cell in cells:
                print(cell.text)
        self.stop_browser(browser)

    def start_browser(self):
        caps = webdriver.DesiredCapabilities().FIREFOX
        caps["marionette"] = True
        return webdriver.Firefox(capabilities=caps)

    def stop_browser(self, browser):
        browser.close()


if __name__ == '__main__':
    FetchEaton()
