Motor Protection relay type SPAM 150 C
The microprocessor based motor protection relay SPAM 150 C is an integrated design current measuring multifunction relay for the complete protection of a.c. motors. The main area of application covers large or medium-sized three-phase motors in all types of conventional contactor or circuit breaker controlled motor
drives. The motor protection relay is available in two versions, one with a making trip contact and
the other with a breaking trip contact.
The relay can also be used in other applications requiring a single-, two- or three-phase over- current and/or overload protection and non-directional earth-fault protection.
