Phoenix Contact now offers a new line of UL 489 Listed circuit breakers – the TMC 8 series. A trip-free design increases safety against closing during an overcurrent event, while the snap-action mechanism eliminates contact welding and reduces contact wear.
These UL 489 Listed circuit breakers provide required fundamental branch
circuit protection. They safely open circuits during overload and short-
circuit events, which prevents the wiring from causing fires.
