Space-saving electronic circuit breaker

Global electrical engineering manufacturer and innovator, Phoenix Contact, has released a new, highly compact, singlechannel electronic circuit breaker – the PTCB.

At just 6mm wide by 106mm high, the super-lean circuit breaker offers excellent space saving circuit protection and potential distribution, says the manufacturer. It also helps technicians save on costs, as less space is required in the control box.

The smart device protects 24 V DC 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. Plus, adding the PTCB to existing applications is quick and easy as the device does not require users to purchase another set of terminals, says Phoenix Contact.

Phoenix Contact says the device is suitable for a wide range of applications as technicians can adjust the amp values on the device from 1 to 8 to tailor the PTCB to their needs and ensure optimal adaptation to the connected load/application. 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 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. The PTCB also offers high-reliability even under extreme ambient conditions. It is suitable for use in temperatures ranging from -25º to 60 ºC, and is shock and vibration resistant, states the manufacturer.

The push-in capability of the PTCB means that connecting the device requires no tools and a lower insertion force when compared to comparable technologies. With the PTCB, connecting the device is both fuss-free and time-saving, says Phoenix Contact.

The portfolio of PTCB electronic circuit breakers features three adjustable devices with different nominal current ranges between one and eight A, and four devices with fixed nominal currents of two, three, four and six A.
