The Mobile latest generation personal protection device.
With peace of mind!

Anyo­ne who wants to use an elec­tri­cal out­let of an exis­ting elec­tri­cal instal­la­ti­on for com­mer­cial pur­po­ses must take appro­pria­te pro­tec­ti­ve mea­su­res in advan­ce. PRCD‑S pro meets this requirement.

Fault-free switching on with gloves

With the PRCD‑S pro, it makes no dif­fe­rence whe­ther users wear gloves or not, thanks to the latest electronics.

Fault-free swit­ching on is pos­si­ble at all times under all ope­ra­ting conditions.

Determining the quality of the protective earth resistance

The PRCD‑S pro not only detects whe­ther the pro­tec­ti­ve earth PE is con­nec­ted, but also deter­mi­nes its qua­li­ty. Swit­ching on is only pos­si­ble if the resis­tance of the pro­tec­ti­ve earth RPE is less than 1kΩ ist.

Thus, the PRCD‑S meets the hig­hest safe­ty requirements.

Self-monitoring device

Self-moni­to­ring device
The PRCD‑S pro moni­tors its­elf. The clas­sic test but­ton is omitted.

  • Func­tion­al test of the resi­du­al cur­rent cir­cuit upon every con­nec­tion to the socket and every 2 hours of ope­ra­ti­on – wit­hout interruptions
  • Relay cont­act test upon each switch-on and switch-off process
  • Moni­to­ring of the resis­tance of the pro­tec­ti­ve earth RPE
  • Indi­ca­ti­on of the device sta­tus and fault signal­ling using inte­gra­ted LEDs

Detection of smooth DC fault currents

Elec­tri­cal loads and equip­ment can gene­ra­te smooth DC fault currents.
If the­se are con­nec­ted to an elec­tri­cal cir­cuit with a Type A fault cur­rent cir­cuit brea­k­er, the­se smooth DC fault curr­ents cau­se the fault cur­rent cir­cuit brea­k­er to not function.

The PRCD‑S pro detects smooth DC fault curr­ents > 6 mA safe!*

DGUV 203–006 konform

DGUV Infor­ma­ti­on 203–006 (DGUV – Ger­man Social Acci­dent Insu­rance) requi­res the use of appro­pria­te pro­tec­ti­ve mea­su­res when con­nec­ting elec­tri­cal equip­ment to unfa­mi­li­ar sockets, e.g. use of a por­ta­ble resi­du­al cur­rent device accor­ding to DIN VDE 0661:

  • Rated dif­fe­ren­ti­al cur­rent I∆n ≤ 30 mA
  • All-pole swit­ching, inclu­ding pro­tec­ti­ve earth
  • No inde­pen­dent restart after res­to­ra­ti­on of voltage

As well as the fol­lo­wing functions:

  • Must not be able to be swit­ched on if the pro­tec­ti­ve earth is inter­rupt­ed or is under voltage
  • Must be swit­ched off if vol­ta­ge is pre­sent at the pro­tec­ti­ve earth during ope­ra­ti­on or if the pro­tec­ti­ve earth is interrupted
  • The pro­tec­ti­ve earth must not be swit­ched off if exter­nal vol­ta­ge is pre­sent on the pro­tec­ti­ve earth
