Phoenix Contact PTCB electronic circuit breaker

Phoenix Contact has released a compact, single-channel electronic circuit breaker — the PTCB. Measuring 6 x 106 mm, the electronic circuit breaker offers space-saving circuit protection and potential distribution. As a result, 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 output or with multiples connected together. Adding the device to existing applications is quick and easy, as it does not require users to acquire another set of terminals.

Technicians can adjust the amp values on the device from 1 to 8 to tailor the circuit breaker to their needs and ensure optimal adaptation to the connected load/application, making it suitable for a wide range of applications. The device also offers considerable flexibility as it can be modified during start-up as well as adjusted at any time to respond to changes in the application.

The unit is equipped with a relay status indicator with a pre-warning LED so that users can see the functional status of each circuit breaker. Shock and vibration resistant, it is operational even under extreme ambient conditions and suitable for use in temperatures ranging from -25 to 60°C. The product’s push-in capability means that connection of the device requires no tools and a low insertion force.

The electronic circuit breaker portfolio 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.
