PTCB series electronic overcurrent protection

PTCB series electronic overcurrent protection

Bridgeable and narrow for high flexibility

At 6.2 mm wide, the PTCB series of electronic circuit breakers the perfect solution for protecting your critical loads. The single-channel PTCB series is Listed to UL 508 and Recognized to UL 2367.  They can be ordered as fixed versions or programmable versions which can be individually adjusted from 1 to 8 A, enabling them to cover a wide range of applications with a single part number. Also available, are versions with NEC Class 2 which eliminates fire and shock hazards. The ability to bridge the PTCB to our CLIPLINE complete portfolio of terminal blocks makes it uniquely flexible for distributing power.

Two different versions of the PTCB are available.  The standard PTCB has a Normally Open (NO) dry contact output to indicate when it has been tripped. The other option is available with status inverted-reset (SI-R).  The SI-R versions have a digital status output that indicates when it has been tripped. It also has a separate digital reset input that enables a tripped device to reset remotely. Both of these single-channel electronic overcurrent protection devices are the perfect solution for protecting your critical loads.
