The Phoenix Contact PTCB TM pluggable thermal-magnetic circuit breaker is one of the industry’s thinnest UL 1077 recognised supplemental protectors.
It is available from authorised distributor DigiKey.
At just 8mm wide, this single-pole circuit breaker saves up to 65% in cabinet space compared to conventional miniature circuit breakers.
It suits applications with high inrush currents, it prevents nuisance tripping during equipment startup, keeping systems running smoothly.
Pair PTCB TM with QUINT power supplies for a seamless protective connection between the power supply and potential distribution.
Users can choose from two trip characteristic curves, M1 and F2, with current ranges from 0.5 to 16A, giving maximum flexibility for diverse applications.
Thanks to CLIPLINE complete terminal block compatibility, wiring is faster and easier.
And by isolating problematic circuits, PTCB TM ensures the rest of the system stays operational, boosting reliability and minimising costly downtime.
PTCB TM circuit breakers provide a clear status indication directly on the device or via remote signalling.
For advanced monitoring, add the optional current monitoring unit (CMU). It displays real-time load status and offers remote signalling with no software or firmware required.
