PTCB SI-R Compact Single-Channel Electronic Circuit Breakers

Phoenix Contact's PTCB series of electronic circuit breakers is now available with status inverted reset (SI-R). These variants have an inverted status output and reset input. The inverted status output simplifies grouped status signal acquisition and the remote reset is indispensable for hard-to-access applications. These single-channel electronic PTCB SI-R overcurrent protection devices are the perfect solution for protecting critical loads.

Like the existing PTCB series, these circuit breakers are available in adjustable ranges from 1 A to 4 A and 1 A to 8 A. They are also available in fixed nominal current versions from 1 A to 8 A. The ability to bridge the PTCB to Phoenix Contact's CLIPLINE complete portfolio of terminal blocks makes it uniquely flexible for distributing power, and the 6.2 mm wide footprint saves space in the control cabinet.
