phase protection relay / panel-mount / digital / programmable
panel-mount, digital, programmable, configurable, for motors
This digital breaker failure relay called the DBF is supplying ground and phase support safety used when a chief circuit breaker wasn't able to fix a system flaw. It has various safety and control features such as a three phases direct trip, an ability to detect if there is a collapse in the operation. It also includes protection from internal arcing, an over current which is ground instantaneous and phase instantaneous.
