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 amp values on the device from 1 to 8 to tailor it to their needs and ensure optimal adaptation to the connected load/application. The device can be modified during start-up and can also be adjusted at any time to respond to changes in the application. It 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 product is operational even under extreme ambient conditions. Suitable for use in temperatures ranging from -25 to 60°C, it is shock and vibration resistant. The push-in capability means that connecting the device requires no tools and a low insertion force.

The portfolio of PTCB 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 of 2, 3, 4 and 6 A.
