The single-channel electronic PTCB protects critical loads from overcurrent. The 6-mm devices can be adjusted specifically to the number of loads requiring protection. They can bridge to the Clipline terminal block portfolio and are compatible with standard terminal blocks and accessories. The devices' adjustable ampere values enable them to cover a range of applications. Users can make modifications even during startup and can respond to changes in the application at any time. In addition to two adjustable devices with different nominal current ranges from 1 to 8 A, four devices offer fixed nominal currents rated at 2, 3, 4 and 6 A.
