As diverse as our fireman's switch is, so are the questions about it!
We know it's not that simple. What does the slave control box do and why a delay circuit? How many surge arresters can I plan for and why? How does the connection to the fire panel work? What is galvanic isolation, what is the difference between a control box and a switch box, how does the fire switch switch off and why can it switch on automatically? How do arc-free switching, undervoltage and cable break detection work? And most importantly, how do I size the QFire (up to the megawatt range)?
