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.
