The only difference between the types SPAC
310 C and SPAC 312 C is the rated current of
the earth-fault protection. For SPAC 310 C it
is 1 A and 5 A and for SPAC 312 C 0.2 A and
1 A.

The unit is intended for the selective short-
circuit and earth-fault protection of radial feed-
ers in solidly earthed, resistance earthed or im-
pedance earthed power systems. The short-cir-
cuit and earth-fault protection is accomplished
by a combined overcurrent and earth-fault mod-
ule.

The control module included in the unit indi-
cates locally by means of LED indicators the
status of maximum three disconnectors or cir-
cuit breakers. Further the module allows status
information from the circuit breaker and the
disconnectors to be transmitted to the remote
control system, and one object, e.g. a circuit
breaker, to be opened and closed via the remote

control system. The status information and the
control signals are transmitted over the serial
bus. Also local control of one object is possible
by using the push-buttons on the front panel of
the control module.

The control module measures and indicates the
three phase currents. The active and reactive
power are measured over two mA-inputs. Exter-
nal measuring transducers are needed. Energy
can be calculated on the basis of the measured
power values or by using one input as an energy
pulse counter. The measured values can be
indicated locally and remotely as scaled values.

The overcurrent protection module also meas-
ures and records the three phase currents and the
neutral current. All the measured and recorded
values are indicated locally and can be transmit-
ted to the remote control system over the SPA
bus.
