I'm working on my FYP - DC mcb using supercapacitors. I need to have a simulation of a DC - mcb to analyse the arc waveforms. Could somebody assist on this?

Welcome to ETO!
Why not use the standard switch model? You might want to add some breakdown device (e.g. a tweaked diode, diac or neon) across the switch contacts.
Have you googled for "circuit breaker spice model"?
