Power supply and device protection Ensure superior system availability with power supplies and device circuit breakers from Phoenix Contact.

Power supplies and device circuit breakers mounted on a DIN rail

Availability is the greatest asset in systems and for machines. Supply your system reliably with the appropriate combination of power supplies and device circuit breakers from Phoenix Contact, while simultaneously protecting it against overload and short circuits.

Select the appropriate products that will help you achieve the required level of availability.

TRIO POWER and QUINT POWER power supplies and the compact CBMC electronic circuit breakers

TRIO POWER, QUINT POWER, and CBMC

Optimally coordinated

When using electronic circuit breakers, a low current reserve is enough to ensure that the device circuit breaker functions reliably.

Our TRIO POWER and QUINT POWER power supplies offer an additional dynamic boost even with a capacity utilization of 100%. This means that the power supply does not have to be overdimensioned. The power in faulty paths is limited and shut down while all other parts of the system continue running.

QUINT POWER power supply and CB TM thermomagnetic device circuit breakers

QUINT POWER and CB TM

Firmly under control with SFB Technology

The QUINT POWER power supply with SFB Technology is the ideal partner for thermomagnetic device circuit breakers. To ensure the safe tripping of thermomagnetic device circuit breakers, it is necessary to supply several times the nominal current for a short period.

The QUINT POWER power supply with SFB Technology provides up to six times the nominal current for 15 milliseconds. Faulty paths are electrically isolated. This reliably protects your system against overload and short circuits.

Structure of a redundant system

Superior availability

Along with the selective protection of individual current paths, a redundant power supply system provides a higher level of system availability.

With the redundant configuration of your power supply and cabling, voltage dips in a primary supply branch, for example, do not affect the output voltage.
