Quattro Transfer Switch/Aux Output rating?

Featured Replies

I need some clarity on the Quattro 48/5000 current capacity. The manual states 'Maximum feed through current (A) 2 x 100' but then there is an 'Auxiliary output (A) 50'. Can anyone shed some more light on the two statements?

Can I assume the AC Out 2 is also called the Auxiliary output and that is rated only at 50A Max? And the 2 x 100 is actually the AC Out 1 capacity? (all of which is when the grid is available obviously)

The transfer switch is on the input of the Quattro. It is called a Quattro (Four in Italian) because it has two inputs and two outputs. The 2 x 100A indicates that each of the inputs has a 100A capacity. The second output has its own contactor that disconnects it if there is an outage (so you put your non-essential loads on that output). That contactor is only rated at 50A. There is no such contacter on AC-out-1, so it can handle the full 100A (if the grid is on of course).

So you are mostly right... :-)

Thanks for the confirmation. I will make double sure not to overload AC-2 Out with anything more than 50A.

Fit a 50A C-curve breaker. Same rule as for cabling, the breaker is there to protect the cable, or in this case the big contactor that has to switch on and off :-)
