The legendary SP ACOM family: More than 300,000 relays in use world-wide

The SPAJ 140 Series relays belong to the SPACOM product family –

already a legend in its field. These products were the first in the worldin intro ducing a substation

automation concept based on a genuine communicating microprocessorcontrolled relay solution.

Today, these products still keep pace with the same enduring protection power.

A world-class relay collection for optimised protection functions

The SPAJ 140 C Series relays serve your network with reliable and versatile technical features:

– The SPAJ 140 C relay comprises a reliable basic relay solution for non-directional overcurrent and

earth-fault protection.

– The SPAJ 141 C relay includes a very sensitive earth-fault input circuit.

– The SPAJ 142 C is a version of SPAJ 140 C with more sensitive earth-fault protection.

– The SPAJ 144 C is the newest member of SPAJ 140 C Series with enhanced protection functionality

and even more protective stages.

The external control input in SPAJ 140 C Series relays enables you to build busbar protection and other

special applications based on blocked overcurrent relays.

Enduring protection

…technology…

The SPAJ 140 Series of Combined Overcurrent and Earth-fault Relays provides your mediumvoltage

network with an optimised composition of protection functions within one relay.

This compact package facilitates combined phase and neutral current relay functions for use

with selective short-circuit and time-overcurrent protection of distribution feeders.

It can also be applied to feeder earth-fault protection in solidly earthed,

resistance earthed and isolated neutral networks.

Completely

…field-proven…

As multi-function solutions, these relays can be flexibly adapted to different kinds of

incoming and outgoing feeders in varying substation environments.You can also use

the SPAJ 140 Series relays for protection of transformers, motors and generators, and as

back-up protection.

Reliable

…through the years…

With numerous years of service in different applications world-wide, the SPAJ 140 Series

Relays serve you with a proven track record of reliability.
