Description
SPAJ140 SPAJ 140 C Overcurrent and earth-fault relay
Features
Three-phase, low-set phase overcurrent unit with definite time or inverse definite minimum
time (IDMT) characteristic
Three-phase, high-set phase overcurrent unit with instantaneous or definite time function
Low-set, non-directional earth-fault unit with definite time or inverse definite minimum time
(IDMT) characteristic
High-set, non-directional earth-fault unit with instantaneous or definite time function
Built-in breaker failure protection function Two heavy-duty and four light-duty output
relays with field-selectable configuration Extensive data communication capabilities over
built-in serial port
Outstanding design flexibility for easy selection of appropriate operation schemes for different
applications
Numerical display of setting values, measured values, memorized fault values, fault codes etc.
Enhanced system reliability and availability due to continuous hardware and software self-supervision with auto-diagnosis
Powerful software support for setting and parametrizing of the relay and for recording of relay parameters with a portable PC.
Application
The combined overcurrent and earth-fault relay SPAJ 140 C is intended to be used for the
selective short-circuit and earth-fault protection of radial feeders in solidly earthed, resistance
earthed or impedance earthed power systems.
The integrated protection relay includes a phase overcurrent unit and an earth-fault unit with
flexible tripping and signalling facilities. The overcurrent and earth-fault relays can also be
used inother applications requiring single-, twoor three-phase overcurrent protection and
nondirectional earth-fault protection. The combined overcurrent and earth-fault relay also features circuit breaker failure protection.
