Littelfuse T2400.0020 - Dual Overcurrent Relay. 400/450V 5A. The T2400 consists of two combined over current relays, intended for protection, or monitoring of generators, power transmissions and consumer supply. A typical application for protection of a generator is for one of the over current functions to trip the generator breaker and the other over current function to trip a nonessential service. Both over current functions could be used to trip 2 levels of nonessential load. The relay detects the highest of the 3 input currents and, on exceeding the preset values, output relays will be activated after preset time delays.

Littelfuse PPI-600V - The PPI-600V is a ground-wire device that allows a trailing-cable ground to be monitored independently of the parallel ground path created when trailing-cable-fed equipment is in contact with the earth. It also allows a trailing-cable ground to be monitored in the presence of stray dc and it prevents inter-machine arcing caused by the voltages induced in the cables.
