I currently design small panels - mostly motor control panels (1, 2, 3 motor) and the owner of the company is asking us to cut back on costs.
One of the items he wants to cut out on is our standard category B Estop - which is usually a simple E-stop with control relay, a reset button and a control power on pilot light.
He would like us to go down to a single Push-pull Estop and no relay whatsoever - just run the power through the E-stop contacts.
Our machines have motors that are completely enclosed. We are only looking at Category B. We don't usually use more than 3A of current.
Does anyone see an issue with this? It just seems strange to not have any kind of MCR relay.
