Click2Contact

Phoenix Contact has released a highly compact, single-channel electronic circuit breaker, the PTCB. At 6 mm wide by 106 mm high, the PTCB electronic circuit breaker offers space-saving circuit protection and potential distribution. It also helps technicians save on costs, as less space is required in the control box.

The smart device protects 24 VDC loads against overload and short circuiting. It can be used as a standalone circuit breaker or with Clipline complete DIN rail terminals and accessories for additional outputs or with multiples connected together. Adding the PTCB to existing applications is quick and easy as the device does not require users to purchase another set of terminals.

Suitable for a wide range of applications, technicians can adjust the trip values on the device from 1 to 8 A to tailor the PTCB to their needs and ensure optimal adaptation to the connected load. The device can also be modified during start-up as well as adjusted at any time to respond to changes in the application.

The device is equipped with a relay status indicator with a pre-warning LED so that users can see the functional status of each circuit breaker, and it is suitable for use in temperatures ranging from -25 to 60°C.

The PTCB range of electronic circuit breakers features three adjustable devices with different nominal current ranges between 1 and 8 A, and four devices with fixed nominal currents of 2, 3, 4 and 6 A.
