SECUTEST ST BASE(10) / PRO and SECULIFE ST BASE(25)
13.3 RPE – Protective Conductor Resis-
tance for Protection Category I DUTs
1
10/25 A RPE measurements are only possible with line
voltages of 115/230 V and line frequencies of 50/
60 Hz.
2
The selected offset value is permanently saved and used in mea-
surements performed in switch positions
A1 to A9 .
3
Connection also via EL1, VL2E, AT3 adapter, AT16DI/AT32DI
➭ Connect the DUT to the test socket.
➭ Contact all conductive parts which are
connected to the protective conductor
with test probe P1.
Special Case: Permanently Installed DUT
➭ Contact all conductive housing parts
with test probe P1.
Meas. Parameter Meaning
Measurement type
Permissible test current IT
Passive: PE(TS) – P1
@ IT = 200 mA/10 A/
25 A
Testing is conducted between the two
protective conductor terminals: at the
test socket
3
and test probe P1.
Active: PE(TS)-P1
@ IP = 200 mA
Same as PE(TS) – P1 , but with line
voltage to the test socket and continu-
ously rising DC test current (PRCDs)
PE(mains) – P1
Perm. connected DUTs
@ IT = 200 mA/10 A
Testing is conducted between the
ground terminal at the mains and
test probe P1.
PE(mains) - P1 clamp
@ IT = 10 A (see section 13.18)
P1 – P2
@ IT =
200 mA/10 A/25 A
Only test instruments with feature H01:
2-pole measurement between test
probes 1 and 2 (see section 13.17)
