The 5SU1354-7KV13: Type A (PSE/SSF) detects pulsating DC residual currents as well as sinusoidal AC — required for circuits feeding single-phase rectifiers, switching power supplies, or variable-speed drives where standard Type AC devices may not trip.
Where it is used
FI/LS protectors of this class mount on DIN rail in consumer units or sub-distribution panels. The 1+N-pole format (switched line, switched neutral) is common in single-phase final circuits where neutral protection is required. The 70 mm depth fits standard enclosures without gland-plate interference.
