Model: 91090

Electromagnetic Relay

Special Features:

A. When the current difference reaches 0.0042 amp in two coils the coil with the higher current will close two sets of spst, normally open contacts, when the same current difference appears in other coil the other two sets of spst normally open contacts will close, and the first set of contacts will open
