For output relays:
Insulation test according to IEC 60255-5
Impulse test according to IEC 60255-5
Insulation resistance test according to IEC 60255-5
Disturbance tests
Current inputs are measured with the
connection box SPEC 3 and a connection cable
of at least two meter. High frequency interference
test voltage, inputs and output between them-
selves and to the fault indicator frame as per:
Common mode acc. to IEC 60255-22-1
Differential mode acc. to IEC 60255-2-1
Common mode acc. to ANSI C37.90.1-1989
Fast transient test IEC 60255-22-4, cl. III
Electrostatic discharge test acc. to
IEC 60255-22-2, cl. III
- contact discharge
- air discharge
Environmental conditions
Enviromental condition tests are made on
SPEF 3A2 C without current sensors.
Specified ambient service temperature range
Transport and storage temperature range
Temperature influence on the operating values over
the specified ambient service temperature range
Climatic environmental tests
- dry heat test acc. to IEC 60068-2-2
- dry cold test acc. to IEC 60068-2-1
- damp heat test acc. to IEC 60068-2-30
