I recently purchased a time delay dual element for circuit protection in my industrial electrical work .Thanks to my knowledge gained in practice I chose this product from the Industrial and Scientific category. This product was easy to install and it has worked great for protecting my equipment against short circuits and overload. The dual element ensures reliable circuit protection and the time delay feature is a plus. The only downside is that IT may not be suitable for all types of circuits. Overall, I'm satisfied with my purchase..
