TemTrip2 is a multi-protection relay for medium or low voltage circuit breakers that is
capable of indicating via LEDs that the load current is picked up or the breaker trips open
and showing various information including the phase current, line voltage and fault current
on the LCD.
The relay is available in three types: for generator protection, feeder circuit protection, and
transformer protection.
