Phoenix Contact PTCB 48 VDC circuit breakers

Friday, 23 February, 2024 | Supplied by: Phoenix Contact Pty Ltd

With the PTCB single-channel circuit breakers from Phoenix Contact, loads with a supply voltage of 48 VDC are now also electronically protected.

The device protection can be combined with the Clipline terminal block range. The circuit breakers can be quickly and easily integrated into the potential distribution and interconnected using standard terminal block accessories. The 6.2 mm overall width matches the terminal block range and saves important space on the DIN rail.

The circuit breaker is available with a fixed nominal value of 2 A or with adjustable nominal current ranging from 1–6 A. This allows the nominal current to be flexibly adapted to the application and reduces storage costs. The LEDs on the front in intuitive traffic light colours and the floating signal contact make the status of the application transparent to users both locally and remotely. This facilitates the clear detection of faults and supports fault localisation and fast recovery. The multi-stage tripping characteristic with dynamic short-circuit detection is optimised for starting different loads.

In addition to the Clipline terminal blocks, the PTCB circuit breakers can also be combined with Phoenix Contact’s 48 VDC QUINT or Trio power supply units.
