Littelfuse · Relay Series
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 · Relay Series
T2200.0080
Overcurrent Relay415/480V5A Latching out. The T2200 has a broad application where all 3 phases or any single phase current detection will function for protection, control or monitoring. The relay detects the highest of the 3 input currents and, on exceeding the preset value, an output relay will be activated after a preset time delay. Available in many versions, varying in supply voltage, measuring currents, and functions.

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.
