Test box for fault protection SIMUlation
SFS/SIMU
Types:
SFS/SIMU
Test box for fault protection SIMUlation for circuit breakers and disconnectors for checking:
- Field interlocks
- System internal interlocks
- Transformer interlocking interlocks
Function
- Simulation of control panels (one control panel per card)
- Comprehensive verification of all interlocking conditions
- Field interlocks
- Internal interlocks
- Transformer interlocking interlocks - Checking the systems without affecting the system condition
Controls and displays
- S1 button, ON for switching error protection ON
- S2 button OFF for switching error protection OFF
- S3 toggle switch for malfunction, for switching error protection deactivated = both LEDs off
- Selector switch (sliding switch) to select the control voltage (60V DC or 220V DC)
- LED, green ON for switching error protection ON, red OFF for switching error protection OFF
Electrical characteristics
- Control voltage 60V DC or 220V DC
- SFS EIN/AUS (blue bushes): External control switching error protection
(same voltage as control voltage) - SFS ON/OFF (yellow bushes): Output of the switching error protection state (medium voltage)
- Signal voltage (SFS on/off (= yellow bushes))
max. Switching current AC1: 250V, 7A
max. Switching current DC1: 30 / 110 / 220V, 7 / 0,25 / 0,12A - EMC-values: UNITRO-Standard in accordance with EN 61000
